Carter made a model of a boat. The length of the actual boat is 45 feet. Carter's model has a length of 7 1/2 inches. What scale did Carter use to build his model?

A) 1 in. = 4 ft

B) 1 in. = 5 ft

C) 1 in. = 6 ft

D) 1 in. = 7 ft

E) 1 in. = 8 ft

Option C) 1 in. = 6 ft

Step-by-step explanation:

Up to know we have the following equality:

45 f = 7 1/2 in

Or what is the same that:

45 f = 7.5 in

If we divide both sides of the equation by 7.5 we will get the equivalence to 1 inch:

45/7.5 f = 7.5/7.5 in

6 = 1 in

So, the correct answer if option C) 1 in. = 6 ft
