A boat can travel 45 km downstream in 50 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 4. How much time will t...
Speed of boat is 10 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 54 km downstream?
The speed of a boat downstream is 20% more than the speed of the boat in still water. If the boat can travel a distance of 288 km upstream in 18 hours, ...

A boat can travel 36 km downstream in 40 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 4. How much time will t...
A boat takes 3 hours to travel 24 km downstream and 4 hours to travel 16 km upstream. What is the speed of the current?
The ratio of the speed of boat in upstream to speed of boat in downstream is 7:9. If the boat can cover a total of 49 km upstream and 81 km downstream i...
If a river is flowing at a rate of 6 km/hr and a boat's speed in still water is 100% higher than the river's speed, and the boat travels 'd' kilometers ...
 A man can row the boat x km downstream and the same distance upstream in 12 hours. Also, he can row the boat 5x km downstream in 10 hours. At what tim...
Two boats A and B start towards each other from two places, 660 km apart. Speed of the boat A and B in still water are 30 km/h and 25 km/h respectively....
