Answer:
![15\dfrac{39}{40} $ inches](https://tex.z-dn.net/?f=15%5Cdfrac%7B39%7D%7B40%7D%20%24%20inches)
Step-by-step explanation:
On the map, 3 inches = 10 miles in real life.
Therefore:
10 miles: 3 Inches
![1$ miles rep $ \dfrac{3}{10}$ inches](https://tex.z-dn.net/?f=1%24%20miles%20rep%20%24%20%5Cdfrac%7B3%7D%7B10%7D%24%20inches)
If the real-life distance between two buildings is 53.25 miles
Distance on the map
![\dfrac{3}{10}$ X 53.25 inches\\=15.975 inches](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B10%7D%24%20X%2053.25%20inches%5C%5C%3D15.975%20inches)
![=15\dfrac{39}{40} $ inches](https://tex.z-dn.net/?f=%3D15%5Cdfrac%7B39%7D%7B40%7D%20%24%20inches)
The distance between the two buildings on the map is therefore: ![15\dfrac{39}{40} $ inches](https://tex.z-dn.net/?f=15%5Cdfrac%7B39%7D%7B40%7D%20%24%20inches)
