Question

In the evening, Joe's family and his grandmother went on a short trip. The total distance covered is $30\text{miles}.$ Calculate the gallons of gasoline required for the trip. Given that, $1\text{qt}$ of gasoline is required to cover $5\text{miles}.$

• A. 1.5

Answer 1

The correct option is A 1.5
Gasoline required to cover $5\text{miles}=1\text{qt}$

$\Rightarrow$ Gasoline required to cover $1\text{mile}=\frac{1}{5}\text{qt}$

$\Rightarrow$ Gasoline required to cover $30\text{miles}=30\times \frac{1}{5}\text{qt}=6\text{qt}$

We know,
$4\text{qt}=1\text{gal}\Rightarrow 1\text{qt}=\frac{1}{4}\text{gal}\Rightarrow 6\text{qt}=\frac{6}{4}\text{gal}=1\frac{1}{2}\text{gal}$

Gasoline required $=1.5\text{gal}$
