Question

The diorama of a town uses the scale 5 inches : 10 miles. If the diorama measures approximately 60 inches across, what is the approximate measure of town?

Answer 1

Answer: 120 miles

Explanation:

We will set up a proportion to solve.

Set up a proportion:

`\displaystyle \frac{5\text{ inches}}{10\text{ miles}} =\frac{60\text{ inches}}{x\text{ miles}}`

Cross-multiply:

5 * x = 60 * 10

Multiply:

5x = 600

Divide both sides by 5:

x = 120 miles
