1. The Beechcraft 1900D is a commuter airplane with a fuel capacity of 665 gallons. The function that represents how the amount of fuel changes as a function of distance flown is
f(x) = -0.9x + 665, where x represents miles flown, and f(x) represents the amount of fuel
remaining. What is the rate of change for this scenario?
