a ship leaves port at noon and has a bearing of 529 degrees

a ship leaves port at noon and has a bearing of 529 degrees west. the ship sails at 20 knots. how many nautical miles south and how many nautical miles west will the ship have traveled by 6:00pm?

Solution

This is a triangle question. S29W, means the ship\'s course is 29 degrees true. (180 + 29) The triangle\'s hypotenuse is 120 nautical miles. (6 hours X 20 knots)

The \"westing\" is 58.2 nautical miles (sin 29 deg x 120 miles)

The \"southing\" is 105.0 nautical miles. (cos 29 deg x 120 miles)
