This lesson focuses on calculating gas mileage, a crucial aspect of consumer math. It explains the concept of miles per gallon (mpg), which represents the distance a vehicle can travel on a gallon of gas. By breaking down the formula, the lesson demonstrates how to calculate mpg using an example: if a car travels 400 miles and uses 20 gallons of gas, the calculation would be 400 miles divided by 20 gallons, resulting in 20 miles per gallon. This knowledge helps consumers make informed decisions about their vehicle's fuel efficiency.
