A man can swim at the rate of `5 kmh^(-1)` in still water A. One km wide river flows at the rate of ` 3 kmh^(-1)` . The man wishes to swim across the river directly opposite to the starting point. How much time will be take to cross the river

A man can swim at the rate of 5 km h^-1 in still water. A 1 - km wide river flows at the rate of 3 km h^-1 The man wishes to swim across the river directly opposite to the starting point. (a) Along what direction must the man swim ? (b) What should be his resultant velocity ? ( c) How much time will he take to cross the river ?

A man wishes to swim across a river 0.5km. wide if he can swim at the rate of 2 km/h. in still water and the river flows at the rate of 1km/h. The angle (w.r.t. the flow of the river) along which he should swin so as to reach a point exactly oppposite his starting point, should be:-
