A pilot wishes to fly from point A to point B, a distance of 100 km on a bearing of 105°. The speed of the plane in still air is 240 km/h. A 20 km/h wind is blowing on a bearing of 210°. Remembering that she must fly on a bearing of 105° relative to the ground (ie the resultant must be on that bearing), find
a) the heading she should take to reach her destination
b) how long will the trip take
I know how to find B, as I just need to take the distance divided by the velocity of the resultant vector. My only problem is finding the heading what she should take. Can someone help explain how I start this question? A diagram would be nice (more of a visual learner) but it isn't needed.
