Ratio of speed of boat in downstream and speed of stream is 7:3, if speed of current is 9 km/hr, then find distance travelled (in km) upstream in 6 hours.
The speed of a boat in still water is 15 km/hr. If the boat covers 120 km in upstream in 12 hours, then find the time taken by the boat to travel 120 km...
A man can row 16 km/hr in still water. If the speed of the current is 4 km/hr, it takes 5 hours more in upstream than in the downstream for the same dis...
A boat's speed in still water allows it to cover 120 km in 8 hours. The current's speed is 20% of the boat's speed. How long will it take the boat to tr...
The downstream speed of a boat is 8 km/hr more than its upstream speed and the ratio of the speed of the boat in still water to the speed of the stream ...
A boat goes 52 km in upstream in 4 hours and takes 3 hours to complete a distance of 15 km in downstream. Find the speed of boat in still water.
A man can row at 5 kmph in still water. If the velocity of current is 1 kmph and it takes him 5 hour to row to a place and come back, how far is the place?
When travelling downstream, a boat takes 5.25 hours to travel 147 km. If the speed of the stream is (3/7)th of downstream speed of the boat, ...
A man can row 5 km/hr in still water. If the speed of the current is 2 km/hr, it takes 4 hours more in upstream than in the downstream for the same dist...
