An aircraft P flying at a constant height has a velocity of (300+j400)km/h. Another aircraft Q at the same height has a velocity of (200+j500) km/h.
Determine a)the velocity of P in relation to Q.
b) the velocity of Q in relation to P

    Ok, you need to learn to do these. We will be happy to critique your reasoning or work.

    Velocityrelativez + VelocityZrelativeground= velocityrelativetoground

    so memorize that. In this case it says
