Two swimmers ...

Question

Two swimmers leaves point A on one bank of river to reach the Point B just opposite to A on the other bank. One of them crosses the river along the straight line A B while the other swims right angeled to the stream and then walk the distance that has been carried away by the stream to get to the point B. What was the velocity u of the walking if both of them reach there simultaneously. Velocity of river is 2.5kmph velocity of swimming is 2.5kmph

simultaneously, the velocity of walking of second swimmer is

A man can swim in still water with a velocity $5 m / s$ . He wants to reach at directly opposite point on the other bank of a river which is flowing at a rate of $4 m / s$ . River is $15 m$ wide and the man can run with twice the velocity as compared with velocity of swimming. If he swims perpendicular to river flow and then run along the bank, then time taken by him to reach the opposite point is:

Q. A swimmer who can swim in a river with speed
