How many cars could this have fueled for a year?

Question

 The Deepwater Horizon oil spill resulted in 4.9 million barrels of oil spilling into the Gulf of Mexico. Each barrel of oil can be processed into about 19 gallons of gasoline. How many cars could this have fueled for a year? Assume an average car gets 20 miles to the gallon, and drives about 12,000 miles in a year.

Answer 1

Lost amount of gallons of gasoline : 4,900,000 times 19 ; that is 93,100,000

 

An average car requires [12,000 miles / (20 miles / gallon )] per year ; that is 600 gallons of gasoline.

 

Number of cars the lost gallons could have fueled for a year is 93,100,000 / 600 that is

 

155 cars
