Answer 1

Answer:

Option D 37.5 miles

Step-by-step explanation:

we know that

The scale on a map is $\frac{1}{5}\frac{in}{mi}$

so

using proportion

Find the actual distance for a length on a map of 7.5 in

Let

x ----> the actual distance

$\frac{1}{5}\frac{in}{mi}=\frac{7.5}{x}\frac{in}{mi}\\ \\ x=7.5*5\\ \\x=37.5\ mi$
