Question

Mona is planning a 1,684 mile driving trip. His car gets an average of 22 mpg,and the cost of gas is about $3.42/gallon. What is the approximate driving costof the trip? Round answer to the nearest whole number.

Answer 1

The distance D, travelled is;

`\text{Distance}=speed* gallon`

Where;

`\begin{gathered} \text{Speed}=22\text{mpg} \\ \text{Distance}=1,684\text{mile} \\ \text{gallon}=(1684)/(22) \\ \text{gallon}=76.55 \end{gathered}`

The total gas that would be used for the trip is 76.55gallon.

But, the cost of gas is about $3.42 per gallon.

Hence, the approximate driving cost of the trip would be;
