A motor boat whose speed is 18km/h in still water. It takes 1 hour more to go 24km upstream than to return downstream to the same spot. Find the speed of the stream.

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

A motorboat goes a down stream in a river and covers the distance between two coastal towns in five hours. It covers this distance upstream in six hours. If the speed of the stream is 4 2 km // hours find the speed of the boat in still water.

The speed of a boat in still water is 8(km)/(hr) . It can go 20 km upstream and return downstream to the engine point in 5 hours 20 minutes. Find the speed of the stream.
