a ship leaves port at 12:00 noon sailing at a bearing 193° measured clockwise from north. if the ship sails 20 knots, how many nautical miles south and how many nautical miles west will the ship have traveled by 6:00pm?
the bearing is 13º west of south
20 knots for 6 hr is 120 nautical miles
south = 120 cos(13º)
west = 120 sin(13º)
