A boat takes 6 hours less to travel a distance downstream than to travel the same distance upstream. If the speed of the boat in still water is 9 km/hr and speed of stream is 3 km/hr. Find the total distance covered by the boat.

A motor boat takes 2 hours to travel a distance of 9 km downstream and it takes 6 hours to travel the same distance against the current. The speed of the boat is still water and that of the current (in km/h) respectively are :

A motor boat takes 2 hours to travel a distance of 9 km downstream and it takes 6 hours tomtravel the same distance against the current.The speed of the boat in still water and that of the current (in km/h) respectively are:

A motorboat takes 6 hours to cover 100km downstream and 30km upstream.If the boat goes 75km downstream and returns back to the starting point in 8 hours,find the speed of the boat in still water and the speed of the stream.

What will be speed of stream, if speed of boat in still water is 45km/hr? A. The time taken by boat to cover 240 km upstream is 4 hours more than time taken by boat to cover same distance in downstream. B. Boat takes total 15 hours to cover 300 km in downstream and upstream.

What is the speed of the boat in still water? I. It takes 2 hours to cover the distance between A and B downstream.II.It takes 4 hours to cover the distance between A and B upstream.
