Actual distance between schools is 158 miles

Explanation:

Using ratio in fraction format:

actual milesinches on map=.14.1

But on the map they are 612 inches apart 132

So we need to change the bottom value to 612

For multiply and divide, what we do to the bottom we also do to the top.

Multiply top and bottom by 612132

actual milesinches on map=.14×132.1×132d=d138132d=d158 miles612 inches
