Question

Car X averages $25.0$ miles per gallon of gasoline and Car Y averages $11.9$ miles per gallon. If each car is driven $12,000$ miles, approximately how many more gallons of gasoline will Car Y use than Car X?

• A. $320$
• B. $480$
• C. $520$
• D. $730$
• E. $920$

Answer 1

Answer: (C)

$520$

Gasoline required by Car $X=\frac{12000}{25}=480$

and

Gasoline required by Car $Y=\frac{12000}{11.9}=1008.4$

$Gasolin{e}_x-Gasolin{e}_y=1008.4-480=528.4$

Closest Option to the Answer is $\left(C\right)$
