The rowing speed of a man relative to water is `5 kmh^(-1)` and the speed of water flow is `3 kmh^(-1)`. At angle to the river flow should he head if he wants to reach a point on the other bank, directly opposite to starting point ?

A boat man can row with a speed of 10 km h^(-1) in still water. If the river flows steadily at 5 km //h , in which direction should the boatman row in order to reach a point on the other bank directly opposite to the point from where he stared ? The width of the river is 2 km .

A river flows with a speed more than the maximum speed with which a person can swim in still water. He intends to cross the river by the shortest possible path (i.e., he wants to reach the point on the opposite bank which directly opposite to the starting point). Which of the following is correct ?

A man wants to cross a river 500 m wide. His rowing speed in still water is 3 kmph. The river flows at a speed of 2 kmph. If the man's walking speed on the shore is 5kmph, (a) find the path he should take to get to the point directly opposite to his starting point in the shortest time. (b) How long does it take to get there?

The width of a rivers is 25m and in it water is flowing with a velocity of 4m//min . A boatman is standing on the bank of the river . He want to sail the boat to a point at the other bank which is directly opposite to him . In what time will he cross the river , if he can sail the boat at 8m//min . relative to the water ?

A man wishes to cross a river of width 120 m by a motorboat. His rowing speed in still water is 3 m//s and his maximum walking speed is 1m//s . The river flows with velocity of 4 m//s . (a) Find the path which he should take to get to the point directly opposite to his starting point in the shortest time. (b) Also, find the time which he takes to reach his destination.
