Question

Solve.

On a map, 1 inch equals 15.4 miles. If two cities are 3.5 inches apart on the map, how far are they actually apart?

Answer 1

They are actually 53.9 miles away.

Explanation:

1 in = 15.4 mi

Set up an equation:

Variable x = number of miles

1/15.4 = 3.5/x

Cross multiply:

1 × x = 15.4 × 3.5

x = 53.9
