It is exactley 5600 miles per hour
I disagree with the above. I get:
86,813,337,600 feet/second
Mach 1 = 761.2 mi/h
(x6)
Mach 6 = 4,567.2 mi/h
(x 3600)
4,567.2 mi/h = 16,441,920 mi/second
(x5280)
16,441,920 mi/second = 86,813,337,600 feet/second
Mach 1 per second is 230,281,663 feet per second.
1100
1,126 ft/s
Yes. Mach 1, speed of sound is about 1114 feet per second. MANY handguns has a muzzle velocity greater than that.
Mach 3.32 is approximately 3.32 times the speed of sound in air. At sea level, where the speed of sound is around 343 meters per second (1,125 feet per second), Mach 3.32 translates to about 1,138 meters per second (3,740 feet per second). This speed is typically associated with high-performance military aircraft and supersonic vehicles.
Mach 0.87 is approximately 87% of the speed of sound in air. At sea level and at standard atmospheric conditions, the speed of sound is about 343 meters per second (1,125 feet per second), so Mach 0.87 would be around 299 meters per second (980 feet per second). This speed is commonly encountered in high-performance aircraft and is significantly faster than typical commercial jet speeds.
Mach 3.6 = 2,740.34 mph
If a car is moving at 100 feet per second, then it is traveling at 100 feet per second.
146.6 feet per second.
About 41 feet per second.
About 4.55 feet per second.
5.583 feet per second.
