The speed of a boat in still water is 9 km/hr. It can go 12 km upstream and 12 km downstream in 3 hours. Find the speed of the stream.

The speed of a boat in still water is 8km/hr It can go 15km upstream and 22km downstream in 5 hours.Find the speed of the stream.

The speed of a boat in still water is 8 km/hr. If the boat can go 15 kms downstream and 22 km upstream in 5 hours, then calculate the speed of the stream.

The speed of a boat in still water is 12 km/h. If the boat covers a distance of 38 km upstream in 4 hours, then the speed of the stream (in km/h) is:

The speed of a boat in still water is 10 km/hr. If it can travel 26 km downstream and 14 km upstream in the same time, find the speed of the stream.

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.

The 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 boat in still water.

The speed of a boat in still water is 11 km/hr. It can go 12 km upstream and return downstream to the original point in 2 hours 45 minutes. Find the speed of the stream.
