A boat takes 5 hours to cover 190 km upstream and 8 hours to cover 416 km downstream. Find the time taken by the boat to cover 528 km upstream and 540 k...
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 goes 60 km upstream in 4 hours and 50 km downstream in 2 hours, then the speed of the boat in still water is
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?
A ship covers a distance of 240 km downstream in a time that is 2 hours shorter than the time it takes to cover the same distance upstream. The ship's u...
The ratio of Alex's boat speed in calm water to the speed of the stream is 5:1, respectively. If the boat can traverse 144 km against the current and 36...
