Two swimmers leave point A on the bank of the river to reach point B lying right across on the other bank. One of them crosses the river along the straight line AB while the other swims at right angles to the stream and then walks the distance that he has been carried away by 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 `v_0=2.0 km//hour` and the velocity `v^'` of each swimmer with respect to water equals to `2.5km` per hour.

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 along the straight line AB while the other swims at right angles to the stream and them walks the distance that he has been carried by the stream to get to point B . what was the velocity v_(0) of his walking if both swimmers reach the destination simultaneously? The stream velocity is u and v is the velocity of swimmer in still water.

Two swimmers start at the same time from point A one bank of a river to reach point B on the other bank, lying directly oppostie to point A. one of them crosses the river along the straight line AB, while the other swims at right angles to the stream and then walks the distance, which he has been carried awayby the stream to get to point B. Both swimmers reach point B at the same time. what was the velocity (assumed uniform) of his walking if velocity of both the swimmers in still water is 2.5 km h^(-1) and the stream velocity is 2 km h^(-1) ?

A river of width 80m is flowing at 6 m/s. A motorboat crosses the river in 10s and reaches a point directly across on the other river bank. The velocity of motorboat in still water is :

A boat has to cross a river.It crosses the river by making an angle of 60^(@) with the bank of the river due to the stream of the river and travels a distance of 600m to reach the another side of the river.What is the width of the river?

A person, reaches a point directly opposite on the other bank of a flowing river, while swimming at a speed of 5 m/s at an angle of 120^(@) with the flow. The speed of the flow must be

A swimmer crosses the river along the line making an angle of 45^(@) with the direction of flow. Velocity of the river is 5 m/s. Swimmer takes 6 seconds to cross the river of width 60 m. The velocity of the swimmer with respect to water will be :

The angle of elevation from a point on the bank of a river of the top of a temple on the other bank is 45^(@) . Retreating 50 m, the observer finds the new angle of elevation as 30^(@) . What is the width of the river?
