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

A man can row a boat with 4km/h in still water, if he is crossing a river where the current is 2 km/h. (a) In what direction will his boat be holded, if he wants to reach a point on the other bank, directly opposite to starting point? (b) If width of the river 4km, how long will the man take to cross the river, with the condition in part (a)? (c) In what direction shou ld he heat the boat if he wants to cross the river in shorest time and what is this minimum time? (d) How long will it take him to row 2 km up the stream and then back to his starting point?

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 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 boatman can row with a speed of 10 kmh^(-1) in still water. River flows at 6 km h^(-1) . If he crosses the river from one bank to the other along the shortest possible path, time taken to cross that river of width 1 km is

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 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 man can row a boat at 4.0km/hr in still water. A river flows at 2.0km/hr. (a) if he is crossing the river, in what direction the oat shou ld go to reach a point directly opposite to his staring point? (b) if the river is 4.0km wide how long will it take him to cross the river? (c) How long will it take him to row 2.0km down the river and then back to his starting point? (d) How long will it take him to row 2.0 km up the river and then back to his starting point? (e) in what direction the boat shou ld go, if he wants to cross he river in teh smallest possible time?

A swimmer can swim with velocity of 12 km/h in still water. Water flowing in a river has velocity 6 km/h. The direction with respect to the direction of flow of river water he should swim in order to reach the point on the other bank just opposite to his starting point is.
