A boat can be rowed in still water at a speed u. The boat is moving downstream in a river in which water flows at a speed v. There is raft floating in water and therefore moving along with water at speed v. Let the boat overtakes the raft at the moment t = 0.
If the raft has covered a distance x during the interval in which boat overtakes the raft, turns back and crosses it again the speed of stream is

A boat goes 20 km downstream in 1 h and the same distance upstream in 2h. The speed of the boat in still water is-

The speed of a boat in still water is 12 kmph . If the boat covers 36 km upstream in 4 hours , what is the speed of stream ?

What is downstream speed when speed of boat in still water and speed of stream are given
