1 point
Car A: drove 300 miles using 15 gallons of gas
Car B: drove 400 miles using 20 gallons of gas
Car C: drove 250 miles using 10 gallons of gas
Car D: drove 500 miles using 25 gallons of gas

Answer 1

To determine which car is the most fuel efficient based on miles per gallon (MPG), we can calculate the MPG for each car using the formula:

\[ \text{MPG} = \frac{\text{miles driven}}{\text{gallons of gas used}} \]

Let's calculate the MPG for each car:

- **Car A:**
\[ \text{MPG} = \frac{300 \text{ miles}}{15 \text{ gallons}} = 20 \text{ MPG} \]

- **Car B:**
\[ \text{MPG} = \frac{400 \text{ miles}}{20 \text{ gallons}} = 20 \text{ MPG} \]

- **Car C:**
\[ \text{MPG} = \frac{250 \text{ miles}}{10 \text{ gallons}} = 25 \text{ MPG} \]

- **Car D:**
\[ \text{MPG} = \frac{500 \text{ miles}}{25 \text{ gallons}} = 20 \text{ MPG} \]

Now, let's compare the results:

- Car A: 20 MPG
- Car B: 20 MPG
- Car C: 25 MPG
- Car D: 20 MPG

**Conclusion:** Car C is the most fuel efficient with 25 miles per gallon.
