To determine how many more miles per gallon Gabi can go if she uses Good Gas instead of Go Gas, we first need to calculate the miles per gallon (MPG) for both brands based on the data provided.
Go Gas
-
5.5 gallons: \[ \frac{170.5 \text{ miles}}{5.5 \text{ gallons}} \approx 31.0 \text{ MPG} \]
-
10.2 gallons: \[ \frac{316.2 \text{ miles}}{10.2 \text{ gallons}} \approx 31.0 \text{ MPG} \]
-
12.0 gallons: \[ \frac{372.0 \text{ miles}}{12.0 \text{ gallons}} = 31.0 \text{ MPG} \]
-
14.5 gallons: \[ \frac{449.5 \text{ miles}}{14.5 \text{ gallons}} \approx 31.0 \text{ MPG} \]
Average MPG for Go Gas: \[ \text{Average} = \frac{31.0 + 31.0 + 31.0 + 31.0}{4} = 31.0 \text{ MPG} \]
Good Gas
-
3.75 gallons: \[ \frac{127.5 \text{ miles}}{3.75 \text{ gallons}} = 34.0 \text{ MPG} \]
-
9.4 gallons: \[ \frac{319.6 \text{ miles}}{9.4 \text{ gallons}} \approx 34.0 \text{ MPG} \]
-
12.6 gallons: \[ \frac{428.4 \text{ miles}}{12.6 \text{ gallons}} \approx 34.0 \text{ MPG} \]
-
16.0 gallons: \[ \frac{544.0 \text{ miles}}{16.0 \text{ gallons}} = 34.0 \text{ MPG} \]
Average MPG for Good Gas: \[ \text{Average} = \frac{34.0 + 34.0 + 34.0 + 34.0}{4} = 34.0 \text{ MPG} \]
Comparison
Now, we can see the average miles per gallon for both types of gas:
- Go Gas: 31.0 MPG
- Good Gas: 34.0 MPG
To find out how many more miles per gallon Gabi can go with Good Gas: \[ 34.0 \text{ MPG} - 31.0 \text{ MPG} = 3.0 \text{ MPG} \]
Thus, the answer is: Gabi can go 3.0 more miles per gallon if she uses gas from Good Gas for her car.
