An airplane flies 572 km in the direction of North, 35° West. The trip takes 2 hours. What is the average velocity of the plane? They provided this answer: v=d/t =572/2 = 286 Numerically this answer is correct, but the final answer, and the solution, are poorly written, missing some very important elements. Rewrite this solution the way it should be written.

An airplane flies 572 km in the direction of North, 35° West. The trip takes 2 hours.
What is the average velocity of the plane?
They provided this answer:
v=d/t
=572/2
=286
Numerically this answer is correct, but the final answer, and the solution, are poorly
written, missing some very important elements. Rewrite this solution the way it
should be written.
