A boat covers 13 km upstream in 52 min. If the speed of the current is 6 km / h, then in how much time will it cover 40 km downstream?
The speed of the boat in still water is 12 km/hr and the speed of the stream is 9 km/hr. A boat goes 105 km downstream with its usual speed but at the t...
If the sum of upstream and downstream speed is 28 km/hr and the speed of the current is 6 km/hr. Then find time taken to cover 50 km in downward?
A man can row his boat with the stream at 14 km/h and against the stream in 8 km/hours. Find the rate of the stream.
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 boy can swim a certain distance downstream in 4 hours and return in 5 hours. If the rate of stream is 3 kmph then what is the speed of boy in still wa...
The speed of a boat in downstream is 20% more than speed of boat in still water. If the boat travels a distance of 90 km upstream in 15 hours then find...
The downstream speed of a boat is 22 km/hr, and its upstream speed is 14 km/hr. Determine the time required for the boat to trave...
The speed of a boat in still water increases by 4 km/hour after each hour. The speed of stream is 3 km/hour. If the boat travelled 60 km in 3 hours in d...
A boat travels from point 'Y' to point 'Z' downstream and then returns to point 'X', which is located midway between 'Z' and 'Y'. The entire trip takes ...
