Baffled at some Relative Motion (M4)

Question:
A car is moving due W and the wind appears, to the driver, to be coming from a direction N60*W. When he drives due E at the same speed the wind appears to be coming from a direction N30*E. If he now travels due S at the same speed, find the apparent direction of the wind.
See I don't know wtf is going on tbh. I drew some diagrams and deduced some equations which didn't really help.
Any help is appreciated.

N60*W ?????What bearing is this?

It means North then 60 degrees West.

What does this mean as a bearing?

300 degrees bearing I believe.
But I solved this yesterday so try it if you want for fun.

m8 which exercise is this ?

It was 1A Q12 or somethinkg but i made a mistake in my doagram hence i thought the solution was wrong but i fixed and it was fone.
I like relative motion though sometimes the situation are abit weird but as soon as my diagram is down it is easy peasy geometry.
