A boat goes 30km upstream and 44km downstream in 10 hours.In 13 hours,it can go 40km upstream and 55km down-stream. Determine the speed of the stream and that of the boat in still water.

A boat goes 30 km upstream and 44 km downstream in 10 hours. In 13 hours, it can go 40 km upstream and 55km down-stream. Determine the speed of the stream and that of the boat in still water.

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 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 24km upstream and 28km downstream in 6 hrs.It goes 30km upstream and 21km downstream in 6(1)/(2) hrs.Find the speed of the boat in still water and also 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.
