Calculate the ratio of the drag force on a jet flying at 1020 km/h at an altitude of 9.5 km to the drag force on a prop-driven transport flying at half that speed and altitude. The density of air is 0.41 kg/m3 at 9.5 km and 0.68 kg/m³ at 4.8 km. Assume that the airplanes have the same effective cross-sectional area and drag coefficient C.
