15英里是多少米?

为你翻译如下,请阅：
【Neil lives in a small town which is 15 miles away from London.】
元宵节快乐!

你这么想：
鸟飞了多远呢?鸟的飞行速度一直是每小时25英里不变的,那么只要能知道鸟飞了多久,就能知道鸟飞了多远.
那么鸟飞了多久呢?鸟从最开始一直飞到两列火车相遇的时候.
那么两列火车要多久才能相遇呢?这取决于洛杉矶到纽约有多远.
理论中,纽约到洛杉矶有大约3000英里,两列火车要相遇需要 3000除以（15+20）,也就是85.7小时.在这段时间里,鸟飞了2142.5 英里.
实际中,一来铁路不一定是直的（确切的铁路距离无法知晓）,二来火车路上走走停停还可能晚点,三来两辆火车不一定就会彼此相遇,最后是鸟一路上也需要花些时间吃喝拉撒——所以答案还真不好说.

设纽约到洛衫矶距离为S英里(设为已知),
两车相遇时用时为
S/(15+20)=S/35,
25*S/35=5S/7,即鸟飞了纽约到洛衫矶距离的5/7.
