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?

• Trig -

the bearing is 13º west of south

20 knots for 6 hr is 120 nautical miles

south = 120 cos(13º)

west = 120 sin(13º)
