A man swims to and fro along the bank of a river with a velocity `v` relative to water. If the velocity of flow is `u`, the average speed of the man (for to and fro motion) is :

A man who can swim at a velocity v relative to water wants to cross a river of width b, flowing with a speed u.

A man who can swim at a velocity v relative to water wants to cross a river of width b, flowing with a speed u.

A man who can swim at a velocity v relative to water wants to cross a river of width b, flowing with a speed u.

A man swims relative to water with a velocity greater than velocity of water. Then

A man swims across the river which flows with a velocity of 3 km/h due east. If the velocity of man relative to water is 4 km/h due north, then what is his velocity and its direction relative to the shore of the river?

A man swims across the river which flows with a velocity of 3 km/h due east.if the velocity of man relative to water is 4 km/h due north, then How far from his starting point will he reach the opposite bank?

A man swim at an angle theta=120^(@) to the direction of water flow with a speed V_(mw) =5 km/hr relative to water.If the speed of water V_(w) =3 km/hr, Find the speed of the man.

A man swim at an angle theta=120^(@) to the direction of water flow with a speed V_(mw) =5 km/hr relative to water.If the speed of water V_(w) =3 km/hr, Find the speed of the man.
