The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
A boat travels downstream at a speed that is (13/12) times its speed in still water. If the boat takes 3 hours to cover 132 km going upstream, how long ...
A boat can cover 66 km upstream and 165 km downstream in 13 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
The speed of the boat in still water is 10 km/hr and the speed of the stream is 5 km/hr. A boat goes 75 km downstream with its usual speed but at the ti...
The speed of a boat in still water is 12 times the speed of the stream. If the difference between the upstream and downstream speed of the boats is 20 k...
A man rows upstream 10 km and downstream 15 km taking 5 hours each. Find the speed of current.

A boat takes 270 minutes to travel 90 km in upstream. The same boat in the same stream takes 120 minutes to travel 50 km in downstream. Find the distanc...
The speed of a boat in still water is 10 kmph. It covers a distance of 60 km downstream in 5 hrs. The speed (in kmph) of the stream is
Distance between a point of A and point B in a river is 32 km and the flow of the stream is from A to B. If the speed of the boat is 10 km/h and speed o...
Speed of a boat in still water to speed of boat in upstream is 9:5. If the boat can travel 390 km in downstream in 5 hours, then find the time taken by ...
