The width of a river is 3 sqrt(3) km. A boat has a velocity of sqrt(3) km/s and starts to cross the river in a direction perpendicular to the bank of the river. If the river is flowing with a velocity 2km/sec, find the distance drifted by the boat.

A man can swim at the rate of 5 km/h in still water. A river 1 km wide flows at the rate of 3 km/h. The man wishes to swim across the river directly opposite to the starting point. (a) Along what direction must the man swim? (b) What should be his resultant velocity? (c) How much time he would take to cross?
