A man can swim at a speed `2ms^(-1)` in still water. He starts swimming in a river at an angle `150^(@)` with direction of flow of water and reaches at the exactly oppsite point on the opposite bank.
(a) Find the speed of flowing water.
(b) If width of river is 1 km then calculate the time taken also

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 is flowing at a speed of 5 km/h in a particular direction. A man, who can swim at a speed of 20 km/h in still water, starts swimming along the direction of flow of the river from point A and reaches another point B which is at a distance of 30 km from the starting point A. On reaching point B, the man turns back and starts swimming against the direction of flow of the river and stops after reaching point A. The total time taken by the man to complete his journey is

A man can swim in still water at a speed of 6 kmph and he has to cross the river and reach just opposite point on the other bank.If the river is flowing at a speed of 3 kmph ,and the width of the river is 2km , the time taken to cross the river is (in hours)

A person aiming to reach the exactly opposite point on the bank of a stream is swimming with a speed of 0.5 ms^-1 at an angle of 120^(@) with the direction of flow of water. The speed of water in the stream, in ms^-1 is ,
