A ship travels downstream from point (A) to point (B) in two hours and upstream in three hours. Then the time taken by log wood to cover the distance from (A) to (B) is .

Boat A travels downstream from Point X to Point Y in 3 hours less than the time taken by Boat B travel upstream from Point Y to Point Z. The distance between X and Y is 20 km, which is half of the distance between Y and Z. The speed of Boat B in still water is 10 km/h and the speed of Boat A in still water is equal to the speed of Boat B upstream What is the speed of Boat A in Still water? (Consider the speed of the current to be the same.) a. 10 k m//h b. 16 k m//h c. 12 k m//h d. 8 k m//h

A streamer goes downstream from one point to another in 9 hours.It covers the same distance upstream in 11 hours.If the speed of stream be 3km/hr ,then the distance between the points is (2)297km (1) 288km (4) 279km (3) 270km

A steamer goes downstream from one port to another in 4 hours. It covers the same distance upstream in 5 hours. If the speed of stream is 2 km/ hr, the distance between the two ports is

A steamer goes downstream from one point to another in 9 hours. IF covers the same distance upstream in 10 hours. If the speed of the stream be 1 km/hr, find the speed of the steamer in still water and the distance between the ports.

A streamer goes downstream from one point to another in 9 hours.It covers the same distance upstream in 10 hours.If the speed of the stream be 1km/hr ,find the speed of the in still water and the distance between the ports.

A steamer goes downstream from one point to another in 7 hours. It covers the same distance upstream in 8 hours. If the speed of stream be 2 km/hr, find the speed of the steamer in still water and the distance between the ports.
