An individual has been driving a passenger vehicle to work, averaging 60 miles a week in a car that averages 22 miles per gallon. The individual plans to purchase a hybrid vehicle that averages 50 miles per gallon. If the individual drives to work 50 weeks a year, how much gas will they save if they switch to a hybrid vehicle for their commute?

76.36 gallons

Explanation:

Miles per week = 60 miles

Passenger vehicle :

Average consumption = 22 mpg

Hybrid vehicle :

Average consumption = 50 miles per gallon

Number of times car is driven to work = 50 weeks per year

Average miles driven per year : number of weeks * average miles driven per week = (50 * 60) = 3000 miles per year

For passenger vehicle :

Gas used per year :

Miles per year / miles per gallon

3000 / 22 = 136.36 gallons

For hybrid vehicle :

3000 / 50

= 60 gallons

Amount of gas saved :

(136.36 gallons - 60 gallons)

= 76.36 gallons

About 76.36 gallons of GAs will be saved by switching to a hybrid vehicle.
