Question

John's SUV gets 18 miles per gallon (mpg). This is half as many mpg as his wife's hybrid car. How many miles per gallon does the hybrid car get?

Answer 1

Answer:

The hybrid car gets 36 miles per gallon (mpg).

Step-by-step explanation:

It is given that John's SUV gets 18 miles per gallon (mpg). This is half as many mpg as his wife's hybrid car.

Let the hybrid car gets x miles per gallon (mpg).

Since the John's SUV miles per gallon (mpg) is half as many mpg as his wife's hybrid car.

$18=\frac{x}{2}$

Multiply both sides by 2.

$18\times 2=\frac{x}{2}\times 2$

$36=x$

Therefore the hybrid car gets 36 miles per gallon (mpg).
