Answer:
the answer will be verified by an expert. Until then, talk to a tutor.
A = L * W
(9/10) = (3/2) * W
Divide both sides (3/2)
(9/10) / (3/2) = W
(9/10) * (2/3) = W
18/30 = W
6/10 = W
W = 3/5 mile
The answer to this, maybe.., is 180
Average speed = total distances / total time
3115.8 / 7.2 = 432.75 mi/h
