Answer:
[tex]\frac{1}{9}\ \frac{in}{ft}[/tex]
Step-by-step explanation:
we know that
To find out the scale factor divide the corresponding dimensions of the model by the corresponding dimensions of the actual
so
[tex]\frac{8}{72}\ \frac{in}{ft}[/tex]
simplify
[tex]\frac{1}{9}\ \frac{in}{ft}[/tex]
That means
1 inch in the model represent 9 feet in the actual
