Question

Hassan filled the gas tank of his car with 5 gallons of gas. If gas cost $5.60/gallon and he drove 140miles, what was his cost per mile?

Answer 1

To find the cost per mile that Hassan incurred, we first need to determine the total cost of the gas he purchased and then divide that cost by the total miles he drove.

1. **Calculate the total cost of the gas:**

\[
\text{Total cost} = \text{Price per gallon} \times \text{Number of gallons}
\]
\[
\text{Total cost} = 5.60 \, \text{dollars/gallon} \times 5 \, \text{gallons} = 28.00 \, \text{dollars}
\]

2. **Calculate the cost per mile:**

\[
\text{Cost per mile} = \frac{\text{Total cost}}{\text{Total miles driven}}
\]
\[
\text{Cost per mile} = \frac{28.00 \, \text{dollars}}{140 \, \text{miles}} = 0.20 \, \text{dollars/mile}
\]

Therefore, Hassan's cost per mile is **$0.20/mile**.
