Question

The scale on a map is 1 in. :30 mi. if it is 6.5 inches from Cincinnati,OH to Columbus, OH, what is the actual distance in miles?

Answer 1

The distance is 195 miles.

Explanation:

In order to find this, we create a proportion. On the left would be the scale factor. On the right would be the Ohio distance.

1in / 30 mi = 6.5in / x mi

Now we can cross multiply to find the distance.

30 * 6.5 = 1 * x

195 mi = x
