A river is flowing with a speed of 1 km h^-1 A swimmer wants to go point C starting from A. He swims with a speed of 5 km h^-1 at an angle theta w.r.t. the river flow. If AB = BC = 400 m

A man wants to swim in a river from A to B and back from B to A always following line AB. The distance between points A and B is S. The velocity of the river current v is constant over the entire width of the river. A The line AB makes an angle α with the direction of current. With what velocity u and at what angle β to the line AB should the man swim to cover distance AB and back in time t?
