An airplane flying into a head wind travels the 2400 miles flying distance between two cities in 6 hours. On the return flight, the same distance is traveled in 5 hours. Find the air speed of the plane and the speed of the wind, assuming that both remain constant. (The air speed is the speed of the plane if there were no wind.) Complete the chart and write a system of equations. Hint: Model each equation after the formula, distance equals rate times time. (d = rt)
