Ramu swims a distance of 3 km each upstream and downstream. The total time taken is one hour. If the speed of the stream is `4` km/h, then find the speed of Ramu in still water.

A steamer goes downstream and covers distance between two ports in 4 hours,while it covers the same distance upstream in 5 hours. If the speed of the stream is 2km/h ,then find the speed of the streamer in still water.

A motorboat goes upstream on a river and covers the distance between two towns on the riverbank in six hours. It covers this distance downstream in five hours. If the speed of the stream is 2 km/h, find the speed of the boat in still water.

If the speed of a boat in still water is 8 km/h and the rate of stream is 4 km/h, then find upstream speed of the boat.

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 boat goes 30km upstream and 44km down stream in 10 hours. In 13 hours, it can go 40km upstream and 55km downstream. If the speed of the boat in still water be x km/h and speed of the stream be y km/h. Then. Find the speed d the boat towards upstream.

A boat goes 30km upstream and 44km down stream in 10 hours. In 13 hours, it can go 40km upstream and 55km downstream. If the speed of the boat in still water be x km/h and speed of the stream be y km/h. Then. Write the speed of the boat towards downstream.

A boat goes 25 km upstream and 33 km downstream in 8 hours. It can also go 40 km upstream and 77 km downstream in 15 hours. Find the speed of the stream and that of the boat in still water.

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.
