Question

Emma's car covers $\frac{12}{5}$ miles for per gallon of fuel consumed. What distance will her car cover using $3$ gallons of fuel?

• A. $\frac{12}{5}mi$
• B. $\frac{36}{5}mi$
• C. $\frac{12}{15}mi$
• D. $\frac{4}{5}mi$

Answer 1

The correct option is B $\frac{36}{5}mi$

Distance covered by the car using one gallon of fuel $=\frac{12}{5}mi$
$\text{Distance covered by car using 3 gallons of fuel = distance covered by car using one gallon of fuel}\times 3$
$=\frac{12}{5}\times 3=\frac{36}{5}$

Hence, Emma's car will cover $\frac{36}{5}mi$ using $3$ gallons of fuel.
