A boat can be rowed at 5 m/s on still water. It is used to cross a 200m wide river from the south bank to the north bank. The river current has uniform velocity of 3 m/s due east.   (a) In which direction must it be steered to cross the river perpendicular to current ?   (b) How long will it take to cross the river in a direction perpendicular to the river flow ?   (c) In which direction must the boat be steered to cross the river in minimum time ? How far will it drift ?
