The speed of the boat in still water is 6 km/hr and the speed of the stream is 3 km/hr. A boat goes 108 km downstream with its usual speed but at the ti...
A boat travelling downstream travels at a speed which is 25% faster than it travels in water that is still. Determine how long it takes the boat to trav...
Ratio of downstream and upstream speed of a boat is 5:2. If the speed of stream is 3 km/h, find the distance travelled by boat in downstream in 2 hours.
When travelling downstream, a boat takes 5 hours to travel 300 km. If the speed of the stream is (2/5)th of downstream speed of the boat, the...
Two boats X and Y start towards each other from two places, 140 km apart. Speed of the boat X and Y in still water are 13km/hr and 15km/hr respectively....
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...
A boat covers 45 km downstream in 90 minutes. If the ratio of the speed of the boat in still water to that of the speed of the stream is 5:3, respective...
The speed of a motorboat in still water is 50 km/hr. If the motorboat travels 120 km along the stream in 1 hour 30 minutes, then the time taken by it t...
The speed of a boat in still water is 12 km/h and the speed of the current is 3 km/h. A person travels 135 kilometers in a boat in the upstream directio...
The speed of current is 18 km/hr. If the speed of the boat in still water had been 7 km/hr more than the original speed, then it would take 8 hours to c...
