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 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 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 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 swimmer crosses a river with minimum possible time 10 Second. And when he reaches the other end starts swimming in the direction towards the point from where he started swimming. Keeping the direction fixed the swimmer crosses the river in 15 sec. The ratio of speed of swimmer with respect to water and the speed of river flow is (Assume contant speed of river & swimmer)

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?
