The speed of a boat in calm water is 4 km/hr greater than the speed of the stream. The boat travels a distance of 280 km downstream and 200 km upstream ...
A boat, whose speed in still water is 25% more than the speed of the current, covers 315 km downstream in _____ hours. The speed of the boat in still w...
A boat’s speed in still water is 1.5 times the speed of the current. It takes the boat 22.5 hours to travel 90 km upstream. If ...
A boat running downstream covers a distance of 36 km in 6 hrs and covering the same distance upstream in 9 hrs. What is the speed of a boat in still water?
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 ...
Speed of boat is 10 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 54 km downstream?
The speed of current is 26 km/hr. If the speed of the boat in still water had been 12 km/hr more than the original speed then it would take 7.5 hours to...
A man can row 25/2 km an hour in still water and he finds that it takes him thrice as long as long to row down the river. The rate of stream is:
If the sum of upstream and downstream speed is 48 km/hr and the speed of the current is 4 km/hr. Then find time taken to cover 84 km in downward?
Ratio of downstream and upstream speed of a boat is 5:2. If the speed of stream is 3 km/h, find the distance travelled by boat in downstream in 2 hours.
