Question

Your friend drives 1,100 miles to visit family in Denver. Her car averages 32 mpg.

a) How many gallons of gas will be needed to drive to the destination? Round to the nearest hundredth, if necessary. gallons 2 points

b) How much CO₂ will be produced by driving to the destination? Round to the nearest whole number. pounds of CO2

Answer 1

a) The number of gallons of gas needed to drive to the destination is computed here as:

= Total distance to be travelled / Mileage of the car

= 1100 / 32

= 34.375

Therefore 34.38 gallons of gas will be needed to drive to the destination here.

b) About 20 pounds of CO2 is produced by burning each gallon of gasoline. Therefore the quantity of CO2 here is computed as:

= 20*Amount of gallons to be used

= 20*34.375

= 687.5 pounds

Therefore 688 pounds is the required amount of CO2 that would be produced by driving to the destination here.
