Question

the equation m=40g gives the distance in miles m that a car can travel using g gallons of gas. if the car has gone 140 miles how much gas was used.

Answer 1

The amount of gas the car used is;

`3.5\text{ gallons}`

Step-by-step explanation:

Given the equation;

`m=40g`

where;

m = distance in miles that a car can travel using g gallons of gas.

If the car has gone 140 miles ;

`m=140\text{ miles}`

Substituting the value of m;

`\begin{gathered} 140=40g \\ g=(140)/(40) \\ g=3.5\text{ gallons} \end{gathered}`

Therefore, the amount of gas the car used is;

`3.5\text{ gallons}`
