Swap space allows the operating system to use disk space as additional RAM when the physical memory is full.
A boat can cover 80 km upstream and 200 km downstream in 14 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 44 minutes to cover 22 km in downstream, then find th...
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...
A boat covers a distance of 57 km upstream in 9.5 hours. If the boat's speed in still water had been doubled, it would have taken only 2 hours to cover...
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...
A man rows upstream 36 km and downstream 51 km taking 3 hours each. Find the man’s speed in still water.
A man can row 8 km/hr in still water. If the speed of the current is 2 km/hr, it takes 5 hours more in upstream than in the downstream for the same dist...
The speed of a boat in still water is 20 km/hr. If the boat covers 90 km in upstream in 9 hours, then find the time taken by the boat to travel 150 km i...
The speed of a boat in still water is 30 km/hr. If the boat covers 240 km in upstream in 12 hours, then find the time taken by the boat to travel 140 km...
Speed of a boat in still water is 11 kmph and speed of stream is 9 kmph. A man rows to a place at a distance of 40 km and come back to starting point. T...
