Question

Automobiles have different fuel economies (mpg), and commuters drive different distances to work or school. Suppose that a state department of transportation is interested in measuring the average monthly fuel consumption of commuters in a certain city. The DOT might sample a group of commuters and collect information on the number of miles driven per day, number of driving days per month, and the fuel economy of their cars. Develop a predictive model for calculating the amount of gasoline consumed, using the following symbols for the data.

G= gallons of fuel consumer per month

M= miles driven per day to and from work or school

D= number of driving days per month

F= fuel economy in miles per gallon

Suppose that a commuter drives 24 miles back and forth to work 20 days each month and achieves a fuel economy of 30 mpg. How many gallons of gasoline are used?

Explanation / Answer

Absolute separation voyaged every day = 24miles

Miles driven every day to and from work or school d number of driving days every month

m = separation voyaged every day * no of days in the month

m = 24 * 20 = 480

mileage in miles per gallon f = 30 mpg

All out gallons of fuel expended every month G = m/f = 480/30 = 16 gallons

Subsequently G = m/f
