To determine how many miles the car has traveled after it has used some of the fuel, we can use the gas mileage formula:

$\text{Distance Traveled} = \text{Miles per Gallon} \times \text{Gallons Used}$

Given:

• The car's fuel tank has a capacity of 16 gallons.
• The car's gas mileage is 30 miles per gallon.

Step 1: Define Gallons Used

For each scenario where the car has a certain amount of gas left in the tank, the gallons used can be calculated by subtracting the gas left from the total capacity of 16 gallons:

$\text{Gallons Used} = 16 - \text{Gas Left}$

Step 2: Calculate Distance Traveled

Once we know how many gallons have been used, we can multiply that by the car's mileage (30 miles per gallon) to find the distance traveled.

Let me know how much gas is left in the tank, and I can calculate the distance for each case!

Would you like to provide the gas amounts, or should I create examples?
