A ship, when moving against the current, can travel a distance of 240 km in 8 hours. If the ship's speed in calm waters is 40 km/hr, how many hours will...
The speed of a boat in downstream and upstream is 30 km/hr and 22 km/hr, respectively. Find the approximate time taken by the boa...
A man can row at 36 km/hr in still water. In a stream which is flowing at 12 km/hr, it takes him 3 hrs to a place and back. How far is the place?
The distance covered by a boat while moving in downstream in a fixed time is 3/4 more than in upstream. The speed of stream is what % of the still water...
The speed of a boat in calm water is 4 km/hr greater than the speed of the stream. The boat travels a distance of 280 km downstream and 200 km upstream ...
A boat travels from point 'Y' to point 'Z' downstream and then returns to point 'X', which is located midway between 'Z' and 'Y'. The entire trip takes ...
Speed of a boat in still water to speed of boat in upstream is 7:4. If the boat can travel 450 km in downstream in 5 hours, then find the time taken by ...
A man can row at a speed of 20 km/hr in still water to a certain upstream point and back to the starting point in a river which flows at 5 km/hr. Find h...
The ratio of the distances traveled by a boat in upstream and downstream is 6:7, respectively, and the total time taken to cover the desired distance is...
The speed of a boat in still water is 6 km/hr and speed of current is 4 km/hr. If time taken to cover a certain distance upstream is 10 hours, then how ...
