**drwls**, Sunday, October 28, 2007 at 4:49pmFor (a), draw and solve a vector diagram.

Air velocity + Airspeed vector = Ground speed vector

For (b) Multiply the Ground speed vector by 2 hours, and the answer will be the displacement vector.

I will be glad to critique your work.

b) I got 585 km.

Did I get the right answers? I was a bit confused by part a because I thought it also involved gravity.
