An airplane travels on a bearing of 245 degrees at an airspeed of 200 kilometers per hour while a wind is blowing 50 kilometers per hour from 140 degrees. Find the ground speed of the airplane and the direction of its track, or course, over the ground.

Answer 1

First, vessels travel on headings, not bearings.

200 @ 245° = (-181.262,-84.524)
50 @ 320° = (-32.134,38.302)
add them up to get
(-213.396,-46.222) = 218 @ 258°
