Question

maya drove 420 miles using 18 gallons of gas. at this rate, how many gallons of gas would she need to drive 357 miles?
□ gallons

Explanation:

Step1: Find miles per gallon rate

$\text{Rate} = \frac{420}{18} = \frac{70}{3}$ miles/gallon

Step2: Calculate gallons for 357 miles

$\text{Gallons} = \frac{357}{\frac{70}{3}} = 357 \times \frac{3}{70}$

Step3: Simplify the expression

$357 \times \frac{3}{70} = \frac{1071}{70} = 15.3$

Answer:

15.3 gallons
