The correct answer is B
A boat, whose speed in still water is 25% more than the speed of the current, covers 810 km downstream in _____ hours. The speed of the boat in still wa...
A boat covers a total distance of 48 km downstream and 48 km upstream in 5 hours. Given that the speed of the stream is 4 km/h, what is the distance the...
Speed of a boat in still water is 9 km/hr. It goes 12 km downstream and comes back to the starting point in three hours. What is the speed of water in t...
Sumit can swim 12 km upstream and 16 km downstream in 5 hours. If ratio of speed of stream to that of speed of Sumit in upstream is 1:2, then find the s...
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?
Speed of a boat in still water is 5times more than the speed of stream. If boat covers 72 km in downstream in 6 hours, then find the time taken by the b...
The velocity of a vessel in calm waters is 4.5 times the speed of the current. If the disparity between the boat's speed when moving against the current...
The speed of current is 10 km/hr. If the speed of the boat in still water had been 8 km/hr more than the original speed, then it would take 7 hours to c...
Boat ‘A’ can cover 160 km in still water in 8 hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 2:3 and the spe...
A boat's speed in calm water exceeds the speed of the current by 12 km/hr. Given that the current's speed is 1.25x km/hr and the boat takes 5 hours to t...
