A man swins in a river with and against water at the rate of `15 kmh ^(-1) and 5 kmh^(-1)` . Find the man's speed in still water and the speed of the river.

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.

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's speed in the direction of flow of a river is 12kmh^(-1) . Against the direction of flow of the river the swimmer's speed is 6kmh^(-1) . Calculate the swimmer's speed in still water and the velocity of the river flow.

A swimmer's speed in the direction of flow of river is 16 km h^(- 1) . Against the direction of flow of river, the swimmer's speed is 8 km h^(-1) . The swimmer's speed in still water and the velocity of flow of the river respectively are

A boat crosses a river of width 1 km by shortest path in 15 min. if the speed of boat in still water is 5 kmh^(-1) , then what is the speed of the river?

A swimmer's speed in the direction of flow of rivers is 16 km h^-1 . The swimmer's speed in still water and the velocity of flow of the river respectively are.

At Deoprayag (Garhwal, UP) river Alaknanda mixes with the river Bhagirathi and becomes river Ganga. Suppose Alaknanda has a width of 12 m, Bhagirathi has a width of 8m and Ganga has a width of 16m. Assume that the depth of water is same in the three rivers. Let the average speed of water in Alaknanda be 20 kmh^-1 and in Bhagirathi be 16 kmh^-1 . Find the average speed of water in the river Ganga.
