A boat covers 13 km upstream in 52 min. If the speed of the current is 6 km / h, then in how much time will it cover 40 km downstream?
A boat travels 42 km against the current and 72 km with the current in a total time of 8 hours. Additionally, it covers a distance of 56 km in still wat...
Motor boat covers a certain distance downstream in a river in 5 hours. It covers the same distance upstream in 7 and half an hour. If the speed of the w...
A man rows upstream 36 km and downstream 51 km taking 3 hours each. Find the man’s speed in still water.

A boat can go 15 km upstream and 21 km downstream in 2 hours. If the speed of the stream is 6km/h, then the time taken (in hours) by the boat to go 21 k...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 20 minutes to cover 20 km in downstream, then find th...
The speed of a boat in still water is 50% more than the speed of the stream such that the boat takes 3 hours to cover 81 km downstream. If the speed of ...
