The speed of the current is 80% lower than the boat's speed in still water. The boat covers 120 km in still water in 8 hours. How long will it take for ...
A boat can cover 130 km in downstream in 10 hours and 120 km in upstream in 12 hours. Find the distance travelled by the boat in still water in 4 hours.
A boatman covers 192 km upstream in 4 hours and 288 km downstream in 4 hours. Find the time taken by the boatman to cover 240 km in still water.
A man can row at 4 kmph in still water. If the velocity of current is 2 kmph and it takes him 8 hour to row to a place and come back, how far is the place?
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?
If Boat goes 80 km upstream in 4 hours and 60 km downstream in 2 hours, then the speed of the boat in still water is
A boat travels 40 km downstream in 5 hours, and the same boat travels 40 km upstream in 8 hours. Find the speed of the boat in still water.
A boat can cover ‘y’ km distance downstream in (t+2.5) hours. The same boat can cover ‘0.25y’ km distance upstream in ‘t’ hours. The time ta...
Ratio of speed of boat in downstream and speed of stream is 9:5, if speed of current is 10 km/hr, then find distance travelled (in km) upstream in 6 hours.
A man rows to a place 221 km away and comes back to the starting point. If the speed of the stream is 2 km/hr and the speed of the boat in still water i...
