The car used 3.5 gallons of gas to travel 140 miles.
Solución
To determine how much gas was used when the car has traveled 140 miles, you can use the given equation:
\[
m = 40g
\]
where:
- \( m \) is the distance traveled in miles.
- \( g \) is the gallons of gas used.
Given:
\[
m = 140 \text{ miles}
\]
**Step 1: Plug the known value into the equation**
\[
140 = 40g
\]
**Step 2: Solve for \( g \)**
\[
g = \frac{140}{40}
\]
\[
g = 3.5
\]
**Answer:**
The car used **3.5 gallons** of gas to travel 140 miles.

To find out how much gas was used, you can rearrange the equation \( m = 40g \) to solve for \( g \). Plugging in the value of \( m = 140 \) miles gives you: \[ 140 = 40g \] Dividing both sides by 40: \[ g = \frac{140}{40} = 3.5 \] So, the car used **3.5 gallons** of gas. Now, isn't it interesting how fuel efficiency can change based on driving conditions and the vehicle's make? Many drivers overlook that factors like rapid acceleration or heavy cargo can dramatically affect how many miles per gallon they get!
