Question

An airplane is flying in the direction 148° with an airspeed of u = 920 kilometers per hour. Because of the wind, its groundspeed and direction are v = 820 kilometers per hour and 140°, respectively (see figure). Find the direction and speed of the wind.

Answer 1

if the wind's vector is w, then

u+w = v
<487,-780> + <x,y> = <527,-628>

So, now you can figure x and y, then get the speed and direction.
