Daily at noon a ship departs from Le Havre bound for New York and conversely, another ship leaves New York bound for Le Havre. The crossing lasts 7
days and 7
nights. During the passage to New York, how many Le Havre-bound ships will the New York-bound vessel meet, with today as its date of departure?

Thought

Mapping ship encounters

OK, let's think it through: the Le Havre to New York ship, set to sail for 7 days, will encounter ships bound for Le Havre departing on the same days, adding up to 7 encounters.

Pinpointing ship encounters

Mapping out the journey: a ship leaves Le Havre for New York today at noon. Ships from New York bound for Le Havre set off daily at noon, with rendezvous on the way.

Mapping ship routes

OK, let me see. Ships travel at uniform speed, departing daily noon. A ship from Le Havre to New York takes 7 days. I’m figuring out ship encounters en route.

Tracking ship departure times

I'm curious about ships from New York, 6 days to 0 days before our Le Havre-bound ship's departure and ones sailing at the same time.

Charting ship paths

I'm piecing together the meeting points of ships from New York departing 6 days before to 7 days after our Le Havre-bound ship, based on their relative positions and speeds.

Figuring out the meet point

I’m working out when the Le Havre-bound and New York-bound ships intersect by comparing their positions. The equation reveals the meeting time in relation to their speeds and initial locations.

Determining departure times

I found that the New York-bound ship departs daily, with possible times from -6 to 7 noon. Considering each day's departure sequence for precise meeting calculations.

Confirming meeting times

I’m checking for New York-bound ship departures from -6 to 7 and ensuring they align with the Le Havre-bound ship's journey, leading to 14 valid meetings.

Counting meeting points

I'm evaluating the days when ships from New York bound for Le Havre cross paths with the Le Havre to New York ship, tallying up to 13 specific days.

Tracking ship routes

Confirming the New York-bound ship's journey from day -6 to day 6. This aligns with the given travel duration, ensuring a total of 13 ships overlapping during the 7-day crossing.

Answer

To determine how many Le Havre-bound ships a New York-bound vessel will meet during its 7-day journey, let's break down the scenario:

  1. Daily Departures:

    • Le Havre to New York: A ship departs every day at noon.
    • New York to Le Havre: Conversely, a ship also departs every day at noon.

  2. Journey Duration:

    • Each crossing takes 7 days and 7 nights.

  3. Meeting Points:

    • When a New York-bound ship departs from Le Havre, it will encounter ships that are:
      • Already en route from New York to Le Havre.
      • Departing New York after the Le Havre-bound ship has set sail.

  4. Calculations:

    • Ships Already En Route:
      • Ships that left New York 6 days before the departure of the New York-bound ship from Le Havre are still on their way. This accounts for 7 ships (from 6 days before up to the day of departure).
    • Ships Departing After:
      • During the 7-day journey, a new ship leaves New York each day. This adds another 6 ships (since the ship departing on the 7th day would arrive at the exact time the New York-bound ship arrives in New York, and they wouldn't meet during the journey).

  5. Total Ships Met:

    • 7 (already en route) + 6 (departing during the journey) = 13 ships.

Therefore, the New York-bound vessel will meet 13 Le Havre-bound ships during its passage.

Answer: 13

Question

Daily at noon a ship departs from Le Havre bound for New York and conversely, another ship leaves New York bound for Le Havre. The crossing lasts 7
days and 7
nights. During the passage to New York, how many Le Havre-bound ships will the New York-bound vessel meet, with today as its date of departure?

Answer

Let’s analyze this step by step to determine how many Le Havre-bound ships the New York-bound vessel will meet during its 7-day crossing.

Assumptions:

  • A ship departs from Le Havre to New York every day at noon.
  • A ship departs from New York to Le Havre every day at noon.
  • The crossing takes 7 days and 7 nights.

Key Points:

  1. The New York-bound vessel: This ship departs today at noon from Le Havre. It will travel for 7 days and 7 nights to reach New York.
  2. Ships already en route: When the New York-bound ship departs today, there are 7 ships already on their way from New York to Le Havre (one for each of the previous 7 days, as each ship departs New York at noon daily). These ships will be encountered by the New York-bound vessel as it travels.
  3. Ships departing after the New York-bound ship: During the 7-day journey, a new ship departs from New York every day at noon. The New York-bound ship will meet these ships on its way.

How many ships will the New York-bound ship meet?

  • Ships already en route from New York to Le Havre:
    • The New York-bound ship will meet the ships that left New York 1, 2, 3, 4, 5, 6, and 7 days before it. This gives 7 ships.
  • Ships that depart New York after the New York-bound ship has left Le Havre:
    • The New York-bound ship will also meet the ships that depart New York during its 7-day journey. These ships are the ones that depart on day 1, 2, 3, 4, 5, 6, and 7. This gives 7 ships as well.

Conclusion:

  • The New York-bound ship will meet 7 ships already en route and 7 ships that depart New York while the New York-bound ship is in transit.

Thus, the total number of Le Havre-bound ships the New York-bound vessel will meet is:

14 ships.

Question

Daily at noon a ship departs from Le Havre bound for New York and conversely, another ship leaves New York bound for Le Havre. The crossing lasts 7
days and 7
nights. During the passage to New York, how many Le Havre-bound ships will the New York-bound vessel meet, with today as its date of departure?

Answer

Let's break down the problem carefully:

  • Departure Times: Every day at noon, one ship departs from Le Havre bound for New York, and another ship departs from New York bound for Le Havre.
  • Journey Duration: Each crossing takes 7 days and 7 nights.

Key Assumptions:

  • The New York-bound ship departs today from Le Havre. We want to know how many Le Havre-bound ships it will meet during its 7-day passage to New York.

Ships Already En Route:

  1. The New York-bound ship will meet ships that are already on their way from New York to Le Havre.
  2. Since the crossing takes 7 days, there will be 7 ships already en route from New York to Le Havre (one ship for each of the previous 7 days).

Ships Departing During the New York-Bound Ship's Journey:

  • In addition, during its 7-day journey, the New York-bound ship will encounter the ships that depart New York after it departs Le Havre.
  • Every day a new ship departs New York at noon, so over the 7 days of the New York-bound ship's journey, it will meet 7 ships that leave New York on each of the following 7 days.

Total Number of Ships Met:

  • Ships that are already en route: 7 ships (one for each of the previous 7 days).
  • Ships that depart after the New York-bound ship has left Le Havre: 7 ships (one for each of the 7 days of the New York-bound ship's journey).

Total:

  • The New York-bound ship will meet a total of 7 (already en route) + 7 (departing after) = 14 Le Havre-bound ships.

Thus, the New York-bound ship will meet 14 ships on its way to New York.

Answer: 14 ships.

Answer

Let's carefully analyze the scenario to determine how many Le Havre-bound ships a New York-bound vessel will meet during its 7-day journey.

Given:

  • Daily Departures:
    • From Le Havre to New York: 1 ship every day at noon.
    • From New York to Le Havre: 1 ship every day at noon.
  • Journey Duration: 7 days and 7 nights (total of 7 days).

Objective:

Determine the number of Le Havre-bound ships (departing from New York) that the New York-bound vessel (departing from Le Havre today) will encounter during its 7-day voyage.

Step-by-Step Analysis:

  1. Ships Already En Route When the New York-Bound Vessel Departs:

    • Departure Time of New York-Bound Vessel: Today at noon (let's denote this as Day 0).
    • Ships Departed from New York Prior to Day 0:
      • Day -6: Left 6 days before Day 0.
      • Day -5: Left 5 days before Day 0.
      • ...
      • Day -1: Left 1 day before Day 0.
      • Day 0: Leaves at the same time as the New York-bound vessel.
    • Total Ships Already En Route: 7 ships (from Day -6 to Day 0).

  2. Ships Departing from New York During the New York-Bound Vessel's Journey:

    • Journey Duration: 7 days (from Day 0 to Day 7).
    • Ships Departing from New York:
      • Day 1: Leaves New York on the first day of the journey.
      • Day 2: Leaves on the second day.
      • ...
      • Day 6: Leaves on the sixth day.
      • Day 7: Leaves on the seventh day.
    • Total Ships Departing During the Journey: 7 ships (from Day 1 to Day 7).

  3. Encountering Ships:

    • Ships Already En Route (7 ships): The New York-bound vessel will meet all these ships as they are heading towards Le Havre.

    • Ships Departing During the Journey (7 ships): The New York-bound vessel will also meet these ships as they are en route to Le Havre during the vessel's voyage.

  4. Potential Overlap on Day 7:

    • On Day 7: The ship departing New York would leave at noon, precisely when the New York-bound vessel arrives in New York.
    • Meeting Point: Since both events occur at the same time and location, they do not meet during the journey.

  5. Adjusting for the Overlap:

    • Excluding Day 7 Ship: The ship departing on Day 7 doesn't count as a meeting during the voyage.

    • Total Ships Met During the Journey:

      • Already En Route: 7 ships
      • Departing During Journey: 6 ships (Days 1 to 6)

    • Total: 13 ships

Conclusion:

The New York-bound vessel will meet a total of 13 Le Havre-bound ships during its 7-day passage from Le Havre to New York.
