Q)
(chatquestion)...Two swimmers leave point A on one bank of the river to reach point B
lying right across on the other bank. One of them crosses the river

the stream to get to point B. What was the velocity u of his walking if
both swimmers reached the destination simultaneously? The stream
velocity vo = 2.0 kmh and the velocity v' of each swimmer with
respect to water equals 2.5 kmh.
