Two war planes travel one above the other at a speed of 3600kmph at two different altitudes. The first one travels at an altitude of 1km above earths surface and the second one travels at an altitude of 11km. The air temperature at 1km altitude is 20°C. The air temperature continuously drops by 6°C for each 1000m altitudes we go up. Determine the Mach number of both aircrafts at their respective altitudes. Assume R = 287 J/kgK; γ=1.4
