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
CO_{2} 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.**
