How much gas in 30 miles cost?

The cost of gas for a 30-mile drive depends on your vehicle's fuel efficiency and the current price of gas. For example, if your car averages 25 miles per gallon and gas costs $4 per gallon, you would need 1.2 gallons for the trip, totaling $4.80. Adjust the calculations based on your vehicle's mileage and local gas prices for a more accurate estimate.
