Question

A car can travel $\frac{12}{5}$ miles per gallon of gas. How far can it go with 3 gallons of gas?

• A. $\frac{36}{5}mi$
• B. $\frac{5}{36}mi$
• C. 7 mi
• D. $\frac{32}{5}mi$

Answer 1

The correct option is D $\frac{32}{5}mi$

Distance covered by the car with one gallon of gas $=\frac{12}{5}mi$
Distance covered by the car with 3 gallons of gas = distance covered by the car with one gallon of gas $\times$ number of gallons
$=\frac{12}{5}\times 3$
$=\frac{12\times 3}{5}=\frac{36}{5}mi$
