Answer 1

Given:

The car used 16 gallons to travel 304 miles.

Let x represent gallons of gasoline needed to travel 342 miles.

Using proportions:

`(16)/(304)=(x)/(342)`

solving for x:

`\begin{gathered} 16*342=304x \\ 5472=304x \\ \\ x=(5472)/(304)=18 \end{gathered}`

ANSWER

18 gallons of gasoline needed to travel 342 miles
