An airplane is heading due north at a speed of 300km/h. If a wind begins blowing from the southwest at a speed of 50km/h(average), calculate (a) the velocity (magnitude and direction) of the plane, and (b) how far off course it will be in 30 min.(adsbygoogle = window.adsbygoogle || []).push({});

Ok, I solved a) 337km/h 6 degrees E of N.

But I dont' understand how to solve part b.

Anyone want to help?
