A man can swim at the rate of 5 km/hr in still water. If the speed of the water is 2 km/hr, then the time taken by him to swim 18 km upstream is
A kayaker covers 64 km upstream and 96 km downstream in 8 hours and 6 hours, respectively. Find the time taken by the same kayaker to cover 140 km in st...
The speed of the boat in still water is 10 km/h and the speed of the stream is 6 km/h. A boat goes 48 km downstream with its usual speed but at t...
If the sum of upstream and downstream speed is 30 km/hr and the speed of the current is 6 km/hr. Then find time taken to cover 84 km in downward?
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...
A man can go on a motorboat with a speed of 12 km/hour in still water to a certain upstream point and return to the starting point in a river that flows...
Speed of boat is 15 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 108 km downstream?
A boat takes half the time to move a certain distance downstream than upstream. the ratio of the boat's speed in still water and that of the current is.
A man takes 2.2 times as long to row a distance upstream as to row the same distance downstream. If he can row 66 km downstream in 2 hours, what is the ...
A steam train covers a certain distance at the same speed. If the steam train had been faster by 8 kilometers per hour, it would have taken 16 hours les...
