To analyze Miguel's gas usage, we can determine how many weeks he can go before needing to refuel, given his car's capacity and his weekly usage.
- Miguel's Car Capacity: 20 gallons
- Weekly Gas Usage: 1.5 gallons per week
To find out how many weeks Miguel can drive before needing to refuel, we can use the following formula:
\[ \text{Number of weeks} = \frac{\text{Car Capacity}}{\text{Weekly Usage}} \]
Substituting the values:
\[ \text{Number of weeks} = \frac{20 \text{ gallons}}{1.5 \text{ gallons/week}} = \frac{20}{1.5} \approx 13.33 \text{ weeks} \]
So, Miguel can go approximately 13 weeks before he needs to refuel.
