An aircraft is flying at Mach 1.34 in air at -30C. What is the speed of the aircraft?

so find the speed of sound at that temperature, then multiply by 1.34
To determine the speed of the aircraft, we need to convert Mach number to actual speed. The Mach number represents the speed of an object relative to the speed of sound in a medium.
The speed of sound in air changes with temperature. At -30°C, the speed of sound in air is approximately 320.25 meters per second (m/s). This value can be found using the empirical formula:
speed of sound = 331.5 + (0.6 * air temperature in degrees Celsius)
Now, let's calculate the speed of the aircraft at Mach 1.34:
speed of aircraft = Mach number * speed of sound
= 1.34 * 320.25 m/s
≈ 428.04 m/s
Therefore, the speed of the aircraft is approximately 428.04 meters per second.
