a plane is seen to travel in a direction [S30 degreesW]. If its ground velocity was 300 km/h and the wind speed is 150 km/h south, what is the plane's velocity relative to the air?

Let denote the vector the plane's velocity and direction through the air, the vector the plane's velocity and course over ground and the velocity and direction of the wind.
