Answer:

32 mi

Step-by-step explanation:

Solve using proportions.

$\frac{\frac{1}{2}in}{8 mi} =\frac{2in}{y}$

Find the scale factor (how to get from left to right)

To get from left numerator to right numerator, multiply by 4.

(1/2) X 4 = 2

The scale factor is 4.

Multiply the left denominator by the scale factor to get "y".

8 mi X 4 = 32 mi

Therefore 2 inches represent 32 miles.
