Rate downstream = (15 + 6) kmph = 21 kmph Rate upstream = (15 – 6) kmph = 9 kmph According to the question, Time = Distance/Speed Hence, Required time = 63/21 + 63/9 = 3 + 7 = 10 hours
When travelling downstream, a boat takes 5.25 hours to travel 252 km. If the speed of the stream is (3/8)th of downstream speed of the boat, ...
The speed of a boat downstream is 20% more than the speed of the boat in still water. If the boat can travel a distance of 288 km upstream in 18 hours, ...
The speed ratio of a stream to the upstream speed of a boat is 1:9. A boat takes 2 hours and 30 minutes to travel 82.5 km downstream. Determine the time...
A boat covers a distance of 150 km while moving in a downstream in 5 hours. When the boat covers a distance of 60 km in still water in 3 hours, then Wha...
Ratio of distance covered by boat in upstream to downstream is 4:3. Time taken in downstream and upstream is 2hr and 4 hr respectively. If speed of boa...
A boat has a speed of 52 km/h in still water. It takes 8 hours to travel from point B to point A downstream. The total distance between the two points ...
The speed of the boat in still water is ‘y’ % more than the speed of the boat in upstream. The time taken by the boat to cover (2d+50) km distance i...
The speed of a boat in calm water is 4 km/hr greater than the speed of the stream. The boat travels a distance of 280 km downstream and 200 km upstream ...
The ratio of the speed of boat ‘A’ in still water, the speed of boat ‘B’ in still water and the speed of the current is 8:5:2, respectively. If ...
A boat goes 45 km upstream in 6 hours and 60 km downstream in 4 hours. If the speed of the current is doubled, how much time will the boat take to trave...
