Question

请教运动物理题目 最好给出详细答案 谢谢了！！

A river flows with a uniform velocity v. A person in a motorboat
travels 1.24km upstream, at which time she passes a log
floating by. Always with the same throttle setting, the boater continues
to travel upstream for another 59.3min and then returns
downstream to her starting point, which she reaches just as the same log
does. Calculate the velocity of the river.

Answer 1

如果我没翻译错的话，少条件，少她回到起始点位置所用的时间

Answer 2

能不能写中文

Answer 3

59.3min时表示时间分还是长度单位米啊？
