What the difference between magnitude and direction?

1. An airplane heads due north at 280 mph. It experiences a 38 mph crosswind flowing in the direction of N60°E. Find the true velocity vector of the airplane in terms of I and j. Then find the true SPEED of the airplane.

An old fashioned pirate ship departs from Pirate Island at a bearing of 30º. The ship  travels 30 km/h for 2 hours when it reaches Buccaneer Bay, where all of the treasure is buried. The ship drifts away from the bray for 4.5 hours at 12 km/h at an unknown bearing. While most of the pirates celebrate pirate things, the navigator wakes up from her nap and sees Pirate Island due East. The angle between the ship’s path and Pirate Island is 105.8º.   a. Find the bearing of the ship’s current location from Buccaneer Bay. b.Find the distance from the ship to Pirate Island.
