Calculate the ratio of the drag force on a jet flying at \( 1200 \mathrm{~km} / \mathrm{h} \) at an altitude of \( 15 \mathrm{~km} \) to the drag force on a prop-driven transport flying at half that speed and altitude. The density of air is \( 0.38 \mathrm{~kg} / \mathrm{m}^{3} \) at \( 10 \mathrm{~km} \) and \( 0.67 \mathrm{~kg} / \mathrm{m}^{3} \) at \( 5.0 \mathrm{~km} \). Assume that the airplanes have the same effective cross-sectional area and drag coefficient \( C \).
