3 A buoy is set as the origin of a coordinate system. At 13.00 a boat is 20 m east and 30 m north of a buoy and has position 20 Vector 30 Find the distance of the boat from the buoy at 13:00. The boat is moving with velocity b Find the position of the boat / seconds after 13:00. . Hence find the shortest distance from the boat to the buoy
