Final answer:
There would be approximately 2.27 gallons of gas left after traveling 68 miles.
Step-by-step explanation:
To determine how many miles of gas would be left after traveling 68 miles, you need to know the gas mileage of the vehicle. Gas mileage is usually measured in miles per gallon (MPG). Let's say the vehicle has a gas mileage of 30 MPG.
To calculate the remaining gas, divide the distance traveled (68 miles) by the gas mileage (30 MPG):
Remaining gas = 68 miles / 30 MPG = 2.27 gallons.
Therefore, there would be approximately 2.27 gallons of gas left after traveling 68 miles.
