A map of your town has a scale of 1 inch to 0.25 mile. There are two roads that are 5 inches apart on the map. Use this informat

egoroff_w [7]

Answer: <u>The 2 roads are 1.25 miles apart.</u>

Step-by-step explanation:

If 1 inch equals .25 miles, then you need to multiply .25 by 5.

Use proportions. Make sure the miles are on the same "side" of the fraction. Side meaning the top or the bottom

$\frac{1}{.25} =\frac{5}{x}$

1 times X equals 1x

.25 times 5 equals 1.25

1.25 divided by 1 equals 1.25.
