Calculate the ratio of the drag force on a jet flying at 920 km/h at an altitude of 9.50 km to the drag force on a prop-driven transport flying at half that speed and altitude. The density of air is 0.409 kg/m³ at 9.50 km and 0.685 kg/m³ at 4.75 km. Assume that the airplanes have the same effective cross-sectional area and drag coefficient C. Number Units
