The correct answer is D
Motor boat covers a certain distance downstream in a river in 20 hours. It covers the same distance upstream in 30 hours. If the speed of the water is 1...
If a boat travels 35 km more in downstream than in upstream in 5 hr and if the speed of the boat in still water is 25 km/hr, then find the distance trav...
Ratio of speed of boat in downstream and speed of stream is 9:5, if speed of current is 10 km/hr, then find distance travelled (in km) upstream in 6 hours.
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 44 minutes to cover 22 km in downstream, then find th...
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...
A boat takes 7 hours to cover 245 km upstream and 9 hours to cover 477 km downstream. Find the time taken by the boat to cover 410 km upstream and 495 k...
If the sum of upstream and downstream speed is 30 km/hr and the speed of the current is 6 km/hr. Then find time taken to cover 84 km in downward?
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 40 minutes to cover 15 km in downstream, then find th...
A boat takes 15 hours to travel 360 km downstream. If it takes 18 hours to travel 288 km upstream, Determine the speed of the str...
