Question

Martin needs to be 48 inches tall to drive a go-kart. His shoes add 1 inch to his height. Write an equation to model this situation.

A. Height = 48 + 1.
B. Height = 48 - 1.
C. Height = 48 * 1.
D. Height = 48 / 1.

Answer 1

The equation modeling the situation where Martin's shoes add 1 inch to his height, and he needs to be 48 inches tall to drive a go-kart, is B. Height = 48 - 1, which means his actual height should be 47 inches without shoes.

Step-by-step explanation:

Martin needs to reach a total height of 48 inches to drive a go-kart, and his shoes add 1 inch to his actual height. To model this situation with an equation, we consider his actual height without shoes (which we'll call Height) plus the extra 1 inch his shoes provide. The equation representing the situation is:

Height + 1 = 48

This can be reorganized to further isolate Height:

Height = 48 - 1

Thus, the correct equation would be B. Height = 48 - 1, meaning Martin's height without shoes must be 47 inches to meet the height requirement with his shoes on.
