Answer:
The second car will produce 50 pounds less carbon than the first auto
Explanation:
Let´s begin with the first auto:
if one gallon of fuel is used in 20 miles, in 600 miles the gallons of fuel consumed are (600 miles * 1 gallon / 20 miles) 30. One gallon of fuel produces 5 pounds CO2, then, 30 gallons will produce (30 gallons * 5 pounds CO2 / 1 gallon) 150 pounds CO2.
The second auto uses 1 gallon fuel per 30 miles, then, in 600 miles, it will use (600 miles * 1 gallon / 30 miles) 20 gallons. If one gallon fuel produces 5 pounds CO2, 20 gallons will produce (20 gallons * 5 pounds CO2 / 1 gallon) 100 pounds CO2.
The second car will then produce 50 pounds less carbon than the first auto
The second auto would produce 50 pounds less carbon (in CO2) than the first auto.
One gallon produces 5 pounds of CO2
The two autos are going on a 600 mile trip
The first gets 20 miles per gallon:
600/20 = 30 gallons
30 gallons x 5 pounds = 150 pounds of CO2
The second gets 30 miles per gallon:
600/30 = 20 gallons
20 gallons x 5 pounds = 100 pounds of CO2
Difference between the amount of CO2 produced by the two autos:
150 - 100 = 50 pounds.
Thus the second auto would produce 50 pounds carbon (in CO2) less than the first autos.
