Problem statement

A jet is flying at 600 mi/h in a direction of 450 North of West. 2.5 minutes later it is flying at 450 mi/h in a direction of 300 North of East.

a) Sketch a vector diagram labeling $V_i$ , $V_f$ , and $\Delta V$.
b) Calculate the average velocity vector in unit-vector notation.
c) Calculate the magnitude and direction of aave.

My work

I am not sure if I did this correctly. Could anyone help?

Thanks in advance, this help is so greatly appreciated

Hi user1530249. This is a site for conceptual questions about physics, not general homework help. If you can edit your question to ask about the specific physics concept that is giving you trouble, I'll be happy to reopen it. See our FAQ and homework policy for more information. – Qmechanic Feb 11 '13 at 15:00
Thanks will try to rephrase – user1530249 Feb 11 '13 at 15:14
