Question

A Ford is traveling 20 mph slower than a Buick. The Buick is traveling at a rate of 65 mph. Let F = the the speed of the Ford. Which formula below would correctly calculate the speed of the Ford?

Answer 1

Answer: The formula to find the speed of the Ford could be F = B - 20.

Since the Ford is 20 mph slower than the Buick, all you have to do is subtract 20 from the speed of the Buick. We know the speed of the Buick, it is 65.

Therefore, the speed of the Buick is 65 - 20 or 45 mph.
