* Mach is a ratio: Mach represents the speed of an object relative to the speed of sound. Mach 0.80 means an object is traveling at 80% the speed of sound.
* Speed of sound varies: The speed of sound changes depending on factors like air temperature and altitude.
To convert Mach 0.80 to miles per hour (mph), you need to know the speed of sound at a specific condition:
1. Find the speed of sound: Look up the speed of sound in standard air (at sea level and 15°C), which is approximately 767 mph.
2. Calculate the speed: Multiply the speed of sound by Mach 0.80: 767 mph * 0.80 = 613.6 mph
Therefore, Mach 0.80 is approximately 613.6 mph in standard air conditions.
Important Note: This calculation is an approximation. The actual speed will vary depending on the specific atmospheric conditions.
