Question

Imagine that you own a car that runs on alcohol made from corn that you grow. You drive your car about 15,000 miles in a year, and you get 250 gallons of alcohol from each acre of corn that you process. If your car gets 20 mi/gal, how many acres of corn would you have to grow to fuel your car for a car?
A. 750 acres
B. 30 acres
C. 1.5 acres
D. 3 acres

Answer 1

So, said you drive your car 15,000m/year and you produce 250 gallon from each acre of corn you grow, your car use 1 gallon per 20miles.
15,000 m/year
250 gallons = 1 acee
20 Mile = 1 gallon
Total gallon = 15,000/20
Total gallon = 750
Since 1 acre is 250 gallons.
Total acre = 750/250
Total acre = 3
You need to have 3 acre to go 15,000 m/year.
