A boat can travel at a speed of `5ms^(-1)` on still water.A boatman wants to cross the river while covering the shortest possible distance.In what direction should he row with respect to the bank,if the speed of the water is `4ms^(-1)`?

A man can swim in still water with a speed of 2 ms^-1 . If he wants to cross a river of water current speed sqrt(3) ms^-1 along the shortest possible path, then in which direction should he swim ?

A boy travels with a speed of 10 ms^(-1) for 30 minute. How much distance does he travel ?

A boat which has a speed of 6km/h in still water crosses a river of width 1 km along the shortest possible path in 20 min. the velocity of the river water in km/h is

A boat which has a speed of 5 km// hr in steel water crosses a river of width 1 km along the shortest possible path in 15 minutes . The velocity of the river water in km// hr is

A boat which has a speed of 5 km// hr in steel water crosses a river of width 1 km along the shortest possible path in 15 minutes . The velocity of the river water in km// hr is

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 .

Two ports, A and B, on a north-south line ar separated by a river of width D. The river flows east with speed u. A boat crosses the river starting from port A. The speed of the boat relative to the river is v. Assume v=2u Q. Suppose the boat wants to cross the river from A to the other side in the shortest possible time. Then what should be the direction of the velocity of boat relative to river?

2 km wide river flowing with a rate of 5 km/hr. A man can swim in the still water with10 km/hr. He wants to cross the river along shortest path find In which direction person should be swim

A boy travels with an average speed of 10 ms^(-1) for 20 min. How much distance does he travel ?

A river is following from west to east at a speed of 5m/minute. A boy on the south bank of the river, capable of swimming at 10 meters/minute in still water, wants to swin across the river in the shortest time, (i) Find the direction in which he should swin, (ii) find the direction when drift along the river is zero.
