A swimmer moving upstream passes a float at point P .After two hour, he returns and at this instant it meets the float again at a distance 15km from the point P .If the swimmer velocity in water remains constant, Then find the speed of river flow.

A steamer going downstream overcame a raft at a point P. 1hr later it turned back and after some time passed the raft at a distance 6 km from the point P. Find the speed of river if speed of river relative to water remains constant.

A man swimming downstream overcomes a float at a point M. After travelling distance D,he turned back and passed the float at a distance of D//2 from the point M. Then the ratio of speed of swimmer with respect to still water to the speed of the river will be

A motor boat going down stream comes over a floating body at a point A . 60 minutes later it turned back and after some time passed the floating body at a distance of 12 km from the point A .Find the velocity of the stream assuming constant velocity for the motor boat in still water.

A float is overcome by a motor boat going downstream at a point A. Thours later it turns back and after some time it passes the float at a distance d km from point A. What is the velocity of stream if the speed of motor remains constant w.r.t. water?

When a boat travels in a river (strictly in a straight line), it can go either in the direction of flow of river (i.e downstream) or in the direction opposite the flow of river (i.e. upstrem ). Thus the boat's actual speed is more than by which it can move in stationary water while travelling downstram (as river's flow speed is added to it) and less while travelling upstream (as the boat moves against the flow of river).Based on the given information answer the following questions A boat going downstream in a following river overcome a raft at a point P. 1 h later it turned back and after some time passed the raft at a distance 6 km from point P. Now, it instead of 6 km they have met at 8 km from point P. Find the speed of river

After reversing its direction ,how much time was taken by the boat to meet the raft again ( i.e. 2^(nd) time) ?

A river is flowing from west to east direction with velocity v. A swimmer standing at the south bank wants to cross the river in order to reach a point just in front of the starting point. If the swimmer can swim at a speed of u w.r.t. the river flow, the angle with the north direction, required to swim is equal to?

A boat covers a certain distance downstream in 5 hours but takes 7 hours to return upstream to the starting point. If the speed of the stream is 3 km/h, then find the speed of the boat.

A man can swim at 8 kmph in still water. He covers an equal distance of 18 km both in upstream and downstream between two points in 6 hours. Find the speed of stream .

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
