During a 4.0 hour adventure race in the desert, a dune begins at a position 200km (E 60 degrees S) of the checkpoint. It then drives to a location of 35km (S) from the checkpoint. Finally, it ends up 85km (W 25 degrees N) of the checkpoint. Determine both its average speed and average velocity. Include a diagram.
Equations:
a^2 = b^2 + c^2 - 2bc cos A
cos A= b^2 + c^2 - a^2/ 2bc
