One gallon of gasoline in an automobile's engine produces on the average 9.5 kg of carbon dioxide, which is a greenhouse gas; that is, it promotes the warming of earth's atmosphere. calculate the annual production of carbon dioxide in kilograms if there are 40 million cars in the united states and each car covers a distance of 5000 mi at a consumption rate of 20 miles per gallon.

9.5 x10¹⁰ kg

Explanation:

20 miles journey consumes gasoline of 1 gallon

5000 miles will consume gasoline of 1/20 x 5000 = 250 gallon

1 car consumes 250 gallon

40 million car will consume 250 x 40 x 10⁶ gallon = 10¹⁰ gallons

1 gallon of gasoline produces 9.5 kg of carbon dioxide

10⁶ gallon of gasoline produces 9.5 x 10¹⁰ kg of carbon dioxide.

b. is the answer hoped i        

it’s previous models   because when i picked that son of a gun’s answer it was wrong look for previous models because they might make it a different letter
