The correct answer is D
A ship requires 9 hours to travel a distance of 216 km downstream and 210 km upstream. If the ratio of the ship's speed in calm waters to the speed of t...
"A boat covers 66 km upstream and 98 km downstream in a total of 9 hours. Determine the time required for the boat to travel 48 k...
The ratio between the time taken by a boat to cover a certain distance in upstream and the same distance in downstream is 5:1 respectively. The same boa...
The speed of a boat in still water is 5 times the speed of the stream. If the difference between the upstream and downstream speed of the boats is 24 km...
Speed of boat is 25 km/hr. Speed of the stream is 20% less than speed of boat. Then find time taken by boat to go 90 km downstream?
The speed of a boat is that of the current of water is 40:3. The boat goes along with the current in 3 hours 8 minutes. It will come back in
A swimmer swims from a point A against a current for 5 minutes and then swims current for next 5 minutes and comes to the point B. If AB is 100meters, t...
A man rows upstream 36 km and downstream 51 km taking 3 hours each. Find the man’s speed in still water.
A boat goes 60 km in upstream in 5 hours and takes 3 hours to complete a distance of 12 km in downstream. Find the speed of boat in still water.
A man can go on a motorboat with a speed of 12 km/hour in still water to a certain upstream point and return to the starting point in a river that flows...
