An airplane is headed northeast, bearing 45◦, with an air speed of 500 miles per hour, with a wind blowing with
bearing 315◦, at a speed of 75 miles per hour. Find the ground speed (to nearest tenth of a mph) and the actual course of the plane (to nearest tenth of a degree).
---------------
It's a direct crosswind --> a right triangle.
The groundspeed is the hypotenuse.
GS =~ 505.6 mi/hr
-----------------
The angle between the heading and the ground track's tangent = 75/500
Angle =~ 8.53 degs
Add that to 045 --> ground track of 53.5 degs
===============
PS Planes don't use fractions of mi/hr (they use knots) or of degrees.
