Question

Suppose you drive an average of 10,000 miles each year. Your gasoline mileage caries inversely with the number of gallons of gasoline you use each ear. Write and graph a model for your average mileage m in terms of the gallons g of gasoline used.

Answer 1

"Average mileage," meaning "average number of miles obtained from one gallon of gasoline," is a rate, which we'll call ' m '.

This m equals\[\frac{ 10000 mi }{ g }\]

g represents the number of gallons of gasoline consumed.

Graph m=10000 mi / g as a function of gallons, g.
