Problems on Boat and Stream

Problems Based on Bond Angle

A man rows 10km upstream and the same distance downstream. The difference in time taken by the man in rowing upstream and downstream is 5min. If the speed of boat is 35km/hr, what is the speed of the stream?

Problems Based on Capillarity and Viscosity

Ram travels 12 miles downstream and upstream. It takes 6 hours more to return than to go downstream. If he doubles his speed and covers the same distance of 12 miles downstream and upstream then it takes 1 hour more to go upstream than to go down stream. Find the speed of stream.

A boat takes 4 hr upstream and 2 hr down the stream for covering the same distance.The ratio of velocity of boat to the water in river is.
