Consider an airplane whose takeoff speed is "240 km/h" and that takes 15 s to take off at sea level. The density of standard air is \rho 1 = 1.225 kg/m3 at sea level and \rho 2 = 1.048 kg/m3 at 1600 m altitude. For an airport at an elevation of 1600 m (such as Denver), calculate the takeoff speed. The takeoff speed at an altitude of 1600 m is km/h.
