Question

The length of the driveway shown on a blueprint is 2 inches. If the actual length of the driveway is 20 ft. what is the scale of the blueprint? A. 1 in. = 1 ft B. 1 in. = 2 ft. C. 1 in. = 10 ft D. 1 in. = 40 ft

Answer 1

Choice C: 1 in = 10 ft

Explanation:

We are told that, according to the blueprint,

2 inches = 20 ft

if we multiply both sides by 2 we get

2 in / 2 = 20 ft / 2

1 in = 10 ft

Hence, we conclude that 1 inch is equal to 10 ft, and therefore, choice C is the correct option.
