A man can row 30 km upstream and 44 km downstream in 10 hrs . Also , he can row 40 km upstream and 55 km downstream in 13 hrs . Find the speed of the man in still water .

A man can row 40km upstream and 5km downstream in 13 hours.Also he can row 30km upstream and 44km downstream in 10 hours.Find the speed of the man in still water and the speed of the current.

A boat covers 32km upstream and 36km downstream in 7 hours.Also,it covers 40km upstream and 48km downstream in 9 hours. Find the speed of the boat in still water and that of the stream.

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.

A boatman rows his boat 35km upstream and 55km downstream in 12 hours and he can row 30km upstream and 44km downstream in 10 hours.Find 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. 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 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. Time is equal to …..

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 equation when boat goes 40km upstream and 55km downstream in 13 hours.
