A man can row boat at 9 kmph in still water. If the velocity of the current is 6 kmph and he takes 2 hour to row to a place and come back, how far is th...
- A boat moves with a downstream speed that is 8 km/hr more than its upstream speed. If the boat’s speed in still water exceeds the current’s speed by 12...
Ratio of speed of boat in downstream and speed of stream is 7:4, if speed of current is 8 km/hr, then find distance travelled (in km) upstream in 7 hours.
A boat can cover 120 km in upstream in 4 hours and 144 km in downstream in 3 hours. Find the speed of the stream.
Speed of a boat in downstream is 50% more than that in upstream. Total time to travel 48 km upstream and 36 km downstream is 6 hours. What is the speed ...
A boat travels 315 km downstream in 7 hours and 135 km upstream in 9 hours. Determine the total time the boat takes to cover 150 ...
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 7:5:2, respectively. If ...
The speed of current is 10 km/hr. If the speed of the boat in still water had been 8 km/hr more than the original speed, then it would take 7 hours to c...
A boat covers a distance of 96 km downstream in 4 hours and returns upstream in 6 hours. Find the speed of the stream.
When travelling downstream, a boat takes 5.25 hours to travel 252 km. If the speed of the stream is (3/8)th of downstream speed of the boat, ...
