(125 × 12 × √8100) ÷ 150 = ? (125 × 12 × 90) ÷ 150 = ? 135000 ÷ 150 = ? ? = 900
A man can row one quarters of a kilometer against the stream in 30/4 minutes and return in 5/2 minutes. The speed of the man in still water is:
In still water, a boat can cover 30 km in 90 minutes. Speed of the stream is 20% of the speed of the boat in downstream. Find the time taken by the boat...
A boat can cover 170 km in downstream in 2 hours and 145 km in upstream in 5 hours. Find the speed of boat in still water.
The boat's speed in still water is 20% greater than the speed of the stream. If it takes the boat 4 hours more to travel 176 km d...
The speed of the stream is 11 km/h. Boat ‘A’ covers 84 km distance against the stream in 6 hours and boat ‘B’ covers 90 km distance against the ...
If the sum of upstream and downstream speed is 30 km/hr and the speed of the current is 5 km/hr. Then find time taken to cover 40 km in downward?
A man can row at 2 kmph in still water. If the velocity of current is 1 kmph and it takes him 4 hour to row to a place and come back, how far is the place?
Boat ‘A’ can cover 180 km in still water in 12 hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 3:4 and the sp...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 35 minutes to cover 35 km in downstream, then find th...
A boy can swim a certain distance downstream in 3 hours and return in 7 hours. If the rate of stream is 4 kmph then what is the speed of boy in still wa...
