The correct answer is A
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.
A boat running downstream covers a distance of 50 km in 2(1/2) hrs and the same distance upstream in 10 hrs. What is the speed of the boat in still water?
A ferry takes 108 minutes to row to place B from another place A along the stream. The distance between place A and place B is 32.4 km. If the speed of ...

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...
A man can row one quarters of a kilometer against the stream in 30/4 minutes and return in 5/2 minutes. The speed of the man in still water is:
The speed of a boat in still water is 20 km/hr. If the boat covers 90 km in upstream in 9 hours, then find the time taken by the boat to travel 150 km i...
A man can row 5 km/hr in still water. If the speed of the current is 2 km/hr, it takes 4 hours more in upstream than in the downstream for the same dist...
A boat takes 20 hours to travel 260 km downstream. The speed of the boat in still water is 125% greater than the speed of the stream. If the boat comple...
