An airplane is flying on a bearing of N 400 W at 500 mph. A strong jet-stream speed wind of 100 mph is blowing at S 500 W. Required:
a. Find the vector representation of the plane and of the wind.
b. Find the resultant vector that represents the actual course of the plane.
c. Give the resulting speed and bearing of the plane.

A. a (-321.393, 383.022) b (-76.40, -64.278)

B. (-397.991, 318.744)

C. a. resulting speed 509.9mph  b. bearing of the plane = 51.6°
