A man can swim at the rate of 5 km//h in still water. A river 1 km wide flows at the rate of 3km h^(-1) . A swimmer wishes to cross the river straight.

A man can row with a speed of 6 km/h in still water. What will be his speed with the stream, if the speed of stream is 2 km/h?

A boat man can row with a speed of 10km/hr in still water.The river flow steadily at 5km/hr and the width of the river is 2km. If the boat man cross the river with reference to minimum distance of approach then time elapsed in rowing the boat will be

A boat man can row with a speed of 10 km/hr. in still water. The river flow steadily at 5 km/hr. and the width of the river is 2 km. if the boat man cross the river with reference to minimum distance of approach then time elapsed in rowing the boat will be:-

A man can swim at the rate of 5 km/h in still water. A river 1 km wide flows at the rate of 3 km/h. 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 he would take to cross?

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 .
