A motor boat can travel at 20 km/h in still water. It will be used to travel between two islands in the ocean 20 km apart. Island B is 30 North of East from island A. The ocean current is 5 km/hr 30 South of West. a) What is the velocity of the boat with respect to the shore (magnitude and direction) needs to be to travel from island A to island B along the shortest possible path? b) How long it will take for the boat to reach the island B traveling along the shortest path?
