Given:
A U.S. Geological Survey map has a scale of 1:24200
There are two buildings that are 3.38 miles apart.
We will find how they are inches apart on the map
First, convert from miles to inches
1 mile = 63 360 inches
So, 3.38 miles = 3.38 * 63 360 inches = 214156.8 inches
The map has a scale of 1:24200
So, using the ratio and the proportions, we will find the length on the map as follows:

Rounding to the nearest hundredth
So, the answer will be: 8.85 inches
