Question
A man can go on a motor boat with a speed of 15 km/hour in still water, he goes to a certain distance upstream and come back to the starting point in a river which flows at a speed of 5km/hour. Find the average speed of motor boat for total journey?
Average speed = (Total distance covered)/(total time taken) = (2×60)/9 =40/3 km/hourMore Boats and streams Questions
