A man can row at 6 kmph in still water. If the velocity of current is 3 kmph and it takes him 8 hour to row to a place and come back, how far is the place?
The ratio of the speed of boats ‘A’ and ‘B’ in still water is 8:9, respectively. The speed of the current is 25% of the speed of boat ‘A’ in...
A boat can cover 12 kilometers in still water in 40 minutes. If the speed of the current is 2 kilometers per hour, then what is the average speed it tak...
A boat can travel 42 km downstream in 60 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 2. How much time will t...
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...
A boy can swim in water with a speed of 15 km/hr in still water. If the speed of the stream is 5 km/hr, what will be the time taken by the boy to cover ...
A boatman takes 10 hours to travel 360 km downstream and 15 hours to cover the same distance upstream. How much time would it take for the boatman to t...
Ratio of speed of boat in downstream and speed of stream is 5:2, if speed of current is 4 km/hr, then find distance travelled (in km) upstream in 6 hours.
The speed of a boat in still water is 30 km/hr. If the boat covers 240 km in upstream in 12 hours, then find the time taken by the boat to travel 140 km...
