Material: Rational Functions Between the speed of 50 miles/hour and 70 miles/hour, your gas mileage is a linear function of the speed at which you drive. Your car gets 40 miles/gal at a speed of 50 miles/hr and 30 miles/gal at a speed of 70 miles/hr. During a one-hour time period, your speed increases from 50 miles/hour to 70 miles/hour at a constant rate. How many gallons of gas does your car burn during this period? First, determine the number...
