A man rows a boat a certain distance downstream in 9 hours, while it takes 18 hours to row the same distance upstream. How many hours will it take him t...
A boat takes 7 hours to cover 259 km upstream and 9 hours to cover 477 km downstream. Find the time taken by the boat to cover 645 km upstream and 660 k...
A boat goes 200 km downstream in 50 hours, and 90 km upstream in 30 hours. The speed of the stream is
The ratio of speed of the boat and the speed of the current is 6:5. If the downstream speed of the boat is 44 km/hr. Then find how much distance will th...
A boy can swim in water with a speed of 13 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 ...
If a boat travels 35 km more in downstream than in upstream in 5 hr and if the speed of the boat in still water is 25 km/hr, then find the distance trav...
The time taken by a boat to travel 'd' kilometers downstream is 8 hours, while the time taken to travel (d - 60) kilometers upstr...
Speed of a boat in still water is 6 times more than the speed of stream. If boat covers 112 km in downstream in 8 hours, then find the time taken by the...
A boat goes 12 km downstream in 2 hr and returns in 3 hr. Find speed of stream.
The speed of current is 40 km/hr. If the speed of the boat in still water had been 10 km/hr more than the original speed then it would take 5.5 hours to...
