A man can row 16 km/hr in still water. It takes him thrice as long to row up as to row down the river. Find the speed of the man against the current.
A man can row at 4 kmph in still water. If the velocity of current is 2 kmph and it takes him 5 hour to row to a place and come back, how far is the place?
A boat covers a distance of 150 km while moving in a downstream in 5 hours. When the boat covers a distance of 60 km in still water in 3 hours, then Wha...
The downstream speed of a boat is 4 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 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 speed of the stream is 15 km/h. Boat ‘A’ covers 140 km distance against the stream in 4 hours and boat ‘B’ covers 105 km distance against th...
A boat can go 15 km upstream and 21 km downstream in 2 hours. If the speed of the stream is 3 km/h, then the time taken (in hours) by the boat to go 21 ...
If the sum of upstream and downstream speed is 22 km/hr and the speed of the current is 4 km/hr. Then find time taken to cover 60 km in downward?
The downstream speed of a boat is 4 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 covers a certain distance upstream in 6 hrs and comes back to starting point with current in 3 hrs, If boat's upstream speed is 15 km/hr, then, f...
