Answer:
The resulting speed of the airplane is 150 Km/h
Explanation:
The airspeed of the plane is 120 Km/h due North. The wind came from West pointing to the East at 90 Km/h
Both speeds are acting in different directions, so they must be added as vectors. Both vectors and the resulting velocity (Vr) are shown in the image below
The magnitude of that velocity can be computed by using Pythagoras's theorem:
The resulting speed of the airplane is 150 Km/h
