Answer:

D. 132.3 miles

Step-by-step explanation:

Create a proportion where x is the actual distance between the two cities.

[tex]\frac{1.1}{15}[/tex] = [tex]\frac{9.7}{x}[/tex]

Cross multiply and solve for x:

1.1x = 145.5

x = 132.3

So, the two cities are 132.3 miles apart.

The correct answer is D. 132.3 miles
