A SUV monitors its fuel consumption as it starts to drive along a hilly highway. The
SUV’s internal computer records the level of fuel in its tank and its odometer
readings periodically, shown in the table below:
Fuel Level (gallons)
Distance (miles)

Compute an underestimate of the SUV’s fuel economy when there are 8.9 gallons of
fuel in its tank, assuming that the rate of fuel consumption is either constantly
increasing or constantly decreasing.
Briefly explain why the value you computed is an underestimate.
What information would you need to improve your approximation of the SUV’s fuel
economy at the 8.9-gallon mark?
