The correct answer is B
A man can go on a motorboat with a speed of 18 km/hour in still water to a certain upstream point and return to the starting point in a river that flows...
The ratio of the speed of a boat in still water to the speed of the stream is 4:1. If the boat takes 10 hours to cover 240 km downstream, find the total...
A Man Rows upstream 36 km and downstream 48 kilometers taking 6 hours each time the speed of the current is.
A boat travels 30 km upstream and 45 km downstream in 6 hours. If the speed of the stream is 4 km/h and the boat’s speed in still water is 8 km/h, wha...
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...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 20 minutes to cover 15 km in downstream, then find th...
A boat running downstream covers a distance of 45 km in 9 hrs and covering the same distance upstream in 15 hrs. What is the speed of a boat in still wa...
A boat running downstream covers a distance of 24 km in 3 hrs while it covers the same distance upstream in 6 hrs. Then speed of the boat in still water is
A boat goes 6km an hour in still water, it takes thrice as much time to go the same distance against the current in comparison to the direction of the c...
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...
