Just wondering if anyone could guide me on this question:

1) You are piloting a small plane, and you want to reach an airport 450 kn due south in 3.0 hours. A wind is blowing from the west at 50.0 km/h. What heading and airspeed should you choose to reach your destination?

First, I drew a triangle on the cordinate gird (X and Y axis). I made one of the legs 50.0 km/h, and the other 450 km.

Ax + Bx = Rx

So Rx = 50.0

Ry = 450

R^2= Rx^2 + Ry^2

R^2= 50^2 + 450^2

R= 452.8 km/h

Is this the correct answer? I really dont know because why then would they include a time (3 hrs.) which I didnt even need or use. I am really stuck on this trouble. Also, am I just trying to find velocity? Whats heading?

Thanks!

BTW - my teacher said this was a pretty easy problem, so it should not be too difficult....
