- Ronit takes a total of 24 hours to travel 128 km downstream and then the same 128 km distance upstream. Additionally, he takes 30 hours to cover 480 km dow...
A man can swim at the rate of 5 km/hr in still water. If the speed of the water is 2 km/hr, then the time taken by him to swim 18 km upstream is
A man can row 7 km/hr in still water. If the speed of the current is 3 km/hr, it takes 6 hours more in upstream than in the downstream for the same dist...
A boat travels 48 km downstream in 4 hours and 24 km upstream in 6 hours. What is the speed of the boat in still water?
A boat covers a distance of 108 km downstream in 3 hours. If the ratio of upstream speed to downstream speed of the boat is 5:9, then find the distance ...
A boat running downstream covers a distance of 36 km in 6 hrs and covering the same distance upstream in 9 hrs. What is the speed of a boat in still water?
A boat takes 20 hours to go 200 km upstream. If the boat doubles its speed, it can cover 200 km downstream in 4 hours. Find the speed of the stream.
The upstream speed of a boat is 12 km/hr. If the boat covers 180 km downstream in 5 hours, find the speed of the current.
A boat can travel 36 km downstream in 45 min. The ratio of the speed of the boat in still water to the speed of the stream is 5: 1. How much time will t...
Speed of a boat in still water is three times the speed of the boat in upstream. If the boat takes 20 minutes to cover 20 km in downstream, then find th...
