A boat takes 8 hours to travel 240 km upstream. If the speed of the boat in still water is 40 km/h, how much time will it take for the boat to travel 12...
Speed of a boat in still water is 5 times more than the speed of stream. If boat covers 147 km in downstream in 7 hours, then find the time taken by the...
A boat can cover 90 km upstream and 225 km downstream in 15 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
The speed of a boat in still water increases by 4 km/hour after each hour. The speed of stream is 3 km/hour. If the boat travelled 60 km in 3 hours in d...
A boat can cover 40 km upstream and 60 km downstream in 13 hour. Also it can cover 50 km upstream and 72 km downstream in 16 hour. Find the speed of boa...
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 7:4:2, respectively. If ...
The ratio between the time taken by a boat to cover a certain distance in upstream and the same distance in downstream is 5:1 respectively. The same boa...
