If a man s speed woth and against the wardr current in a river be 15 km h^(-1) and 5 km h^(-1) then tind out the man s speed in still warer and the speed of the river.

A man desires to swim across the river in shortest time. The velcoity of river water is 3 km h^(-1) . He can swim in still water at 6 km h^(-1) . At what angle with the velocity of flow of the river should he swim ?

The speed of a man along with the river is 20km/h and speed of the man against the river current is 10km/h. calculate the speed of the man in still water and speed of the river.

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 :

A swimmer crosses the river along the line making an angle of 45^@ with the direction of flow. Velocity of the river water is 5(m)/(s) . Swimmer takes 12 seconds to cross the river of width 60 m. The velocity of the swimmer with respect to water will be:

A swimmer crosses a river with minimum possible time 10 Second. And when he reaches the other end starts swimming in the direction towards the point from where he started swimming. Keeping the direction fixed the swimmer crosses the river in 15 sec. The ratio of speed of swimmer with respect to water and the speed of river flow is (Assume contant speed of river & swimmer)

man wants to swim across a river of which 200 m along the shortest path . If the speed of river stream is 3 km h^(-1) and speed of swimmer in still water is 5 km h^(-1) , then the time of crossing the river is

Show that the direction of the shortest route is at right angles to the river when the velocity of the swimmer is greater than that of the river. Show also that when the velocity of the swimmer is less than that of the river, the direction is tan^(-1)v//sqrt(u^(2)-v^(2)) where v= velocity of swimmer and u= velocity of river.

A swimmer can swim with velocity of 12 km/h in still water. Water flowing in a river has velocity 6 km/h. The direction with respect to the direction of flow of river water he should swim in order to reach the point on the other bank just opposite to his starting point is.
