1. ## knots

A sailboat leaves port on a bearing of S72W. After sailing for two hours at 12 knots, the boat turns 90 toward the south. After sailing for three hours at 9 knots on this course, what is the bearing to the ship from port? Round your answer to the nearest 0.1.

hm...I know I am suppose to be able to find two lengths of this triangle by converting two hours at 12 knots and 3 hours at 9 knots into a distance...right? How do I go about doing this? Thanks much.

1 knot = 1 natical mile per hour

so 2 hours at 12 kts = 24 nm

3 hours at 9 kts = 27 nm
