When travelling downstream, a boat takes 5.25 hours to travel 147 km. If the speed of the stream is (3/7)th of downstream speed of the boat, ...
A boat can travel 72 km upstream and 108 km downstream in 5 hours. Find the speed of the boat in still water if the ratio of the ...
Speed of a boat in still water to speed of boat in upstream is 11:7. If the boat can travel 300 km in downstream in 5 hours, then find the time taken by...
Two boats X and Y start towards each other from two places, 155 km apart. Speed of the boat X and Y in still water are 14 km/hr and 17 km/hr respectivel...
Boat ‘A’ can cover 160 km in still water in 8 hours. In still water, if the ratio of the speed of boat ‘A’ to that of ‘B’ is 4:3 and the spe...
If a river is flowing at a rate of 6 km/hr and a boat's speed in still water is 100% higher than the river's speed, and the boat travels 'd' kilometers ...
A boat can cover 72 km upstream and 180 km downstream in 12 hours. Speed of the stream is how much less than the speed of the boat in still water if the...
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...
In still water, a boat can cover 30 km in 90 minutes. Speed of the stream is 20% of the speed of the boat in downstream. Find the time taken by the boat...
A boat goes 8 km an hour in still water, but takes twice as much time in going the same distance against the current. The speed of the current (in km/ho...
