Question

My car gets 23 miles per gallon at 60 miles per hour. Is the number of miles I can drive at 60 miles per hour a linear function of the number of gallons of gas in the tank? Explain your reasoning.

Answer 1

9514 1404 393

Answer:

yes

Explanation:

The constant ratio (23 mi)/(1 gal) tells you the number of miles is a linear function of the number of gallons.

miles = (miles/gallon) × gallons

miles = constant × gallons . . . . . a linear function of gallons
