分岔口X
我要送餐到A栋和C栋,最终返回B栋的仓库
我的左边是A栋 右边是B栋,B栋的右边是C栋,
A栋连接我所站的位置再连接B栋再到C栋是直线,
一种路线先去A栋,再去C栋,再返回B栋
一种路线先去C栋,再去A栋,再返回B栋

Mapping out routes

I’m analyzing the distances between buildings A, B, and C to determine which route is longer and where the extra distance is.

Piecing together positions

I'm thinking through the layout of buildings A, B, and C, noting that P connects linearly with A, B, and C, forming a straight line.

Charting routes

I'm mapping out two routes: one from P to A to C to B, and another from P to C to A to B, to determine which is longer based on respective distances.

Evaluating route lengths

I'm figuring out which route is longer by comparing distances. Route 2 is longer by yy, the distance from P to B, as Route 1 is longer by xx.

Mapping the longer route

I'm noting that the longer route involves traveling from P to C, then backtracking to A, unlike the shorter direct route from P to A.

Comparing route lengths

It's interesting to see that the longer route includes an extra distance of y, which is the distance from P to B, contrasting with the shorter direct route.

Evaluating route length

Interestingly enough, the longer route traverses P to C, then C to A, and finally A to B, extending the journey by the distance from P to B.

उत्तर

根据你的描述,建筑物的位置关系可以表示为一条直线:

A栋 —— 你的位置(P) —— B栋 —— C栋

你有两条路线:

  1. 路线一:P → A栋 → C栋 → B栋
  2. 路线二:P → C栋 → A栋 → B栋

我们来计算这两条路线的总距离,并比较哪条更长。

假设距离:

  • P 到 A栋的距离为 x
  • P 到 B栋的距离为 y
  • B栋到 C栋的距离为 z

路线一的总距离:

  • P 到 A栋:x
  • A栋到 C栋:x + y + z(因为要经过 P 到 B栋 再到 C栋)
  • C栋到 B栋:z

总计:x + (x + y + z) + z = 2x + y + 2z

路线二的总距离:

  • P 到 C栋:y + z
  • C栋到 A栋:x + y + z
  • A栋到 B栋:x + y

总计:(y + z) + (x + y + z) + (x + y) = 2x + 2y + 2z

比较:

  • 路线二的总距离 2x + 2y + 2z
  • 路线一的总距离 2x + y + 2z

路线二比路线一多走了 y 的距离,即从你的位置 P 到 B栋的距离。

结论:

先去 C栋,再去 A栋,然后返回 B栋的路线更长。具体来说,这条路线比先去 A栋再去 C栋的路线多走了从你的位置 P 到 B栋的距离 y
