The distance is 750 miles.

Step-by-step explanation:

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

1in / 300 mi = 2.5in / x mi

Now we can cross multiply to find the distance.

300 * 2.5 = 1 * x

750 mi = x
