* Mach Number: Represents the ratio of an object's speed to the speed of sound.
* Speed of Sound: Varies with temperature and altitude, but at sea level and standard temperature (15°C or 59°F), it's approximately 767 mph.
Calculation:
1. Mach 3.5 means the object is traveling 3.5 times the speed of sound.
2. Multiply the speed of sound by the Mach number: 767 mph * 3.5 = 2684.5 mph
Therefore, Mach 3.5 is approximately 2684.5 mph.
