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

Answer:

The amount of gas the car used is;

$3.5\text{ gallons}$

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;

$\begin{gathered} 140=40g \\ g=\frac{140}{40} \\ g=3.5\text{ gallons} \end{gathered}$

Therefore, the amount of gas the car used is;

$3.5\text{ gallons}$
