The correct answer is B
The speed of a boat in still water is 8 km/hr and speed of current is 4 km/hr. If time taken to cover a certain distance upstream is 12 hours, then how ...
A boat moves at 40 km/hr downstream and 10 km/hr upstream. How long will it take to cover 150 km in still water?
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 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 ...
- A boat moves with a downstream speed that is 8 km/hr more than its upstream speed. If the boat’s speed in still water exceeds the current’s speed by 12...
A boat running downstream covers a distance of 30 km in 2 hrs and covering the same distance upstream in 10 hrs. What is the speed of a boat in still wa...
Speed of boat is 15 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 108 km downstream?
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 4:3 and the spe...
Speed of current is equal to 15% of speed of boat in still water. If the boat takes 3 hours to cover 120 km in still water, then find the time taken by ...
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:
