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.

A boat goes 2 km upstream and 3 km downstream in 45 minutes while it goes 3 km upstream and 9 km downstream in 90 minutes. Whatis the speed (in km/hr) of boat when going down stream?
