Velocity of the other plane with respect to Earth =
Velocity of the other plane w.r.t. her plane
+ Velocity of her plane w.r.t. Earth
Perform the vector addition
That doesn't require me to find the x and y components of those vectors, does it?
Yes it does. It's not hard.
Call North the +y direction and east the +x direction.
It is not clear to me if "W 20.0 degrees S" means "20 degrees west of south" or "20 degrees south of west". You will need to clarify the terminology to answer the question.
So, would the components look something like this:
450cos200
450sin200
350cos130
350sin130
