A man can row at 2 kmph in still water. If the velocity of current is 1 kmph and it takes him 4 hour to row to a place and come back, how far is the place?
A boy can swim a certain distance downstream in 5 hours and return in 7 hours. If the rate of stream is 3 kmph then what is the speed of boy in still wa...
If the sum of upstream and downstream speed is 26 km/hr and the speed of the current is 5 km/hr. Then find time taken to cover 72 km in downward?
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 racer can row 45/2km/h in still water. If the speed of river is 12.5 km/h, it takes him 40 minutes to row to a place and back, how far off is the...
The downstream speed of a boat is 6 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 ...
The downstream speed of a boat is 48 km/hr, while its upstream speed is 32 km/hr. The boat takes 10 hours to travel a distance of (p + 40) km downstream...
Speed of a boat in still water to speed of boat in upstream is 9:5. If the boat can travel 390 km in downstream in 5 hours, then find the time taken by ...
A boat running downstream covers a distance of 50 km in 2(1/2) hrs and the same distance upstream in 10 hrs. What is the speed of the boat in still water?
Speed of a boat in still water is 4 times more than the speed of stream. If boat covers 126 km in downstream in 7 hours, then find the time taken by the...
