Answer 2

Answer:

10 gallons of gas

Step-by-step explanation:

Create a proportion, where x is the number of gallons she will use if she drives 75 miles:

$\frac{15}{2}$ = $\frac{75}{x}$

Cross multiply and solve for x:

15x = 150

x = 10

So, she will have to use 10 gallons of gas to drive 75 miles
