This is the rough formula.
Mach = velocity/speed of sound
This is rough because conditions are truly variable, but............
79 Mach = velocity/768 mph
= ~606070 miles per hour

∙ 13y agoThe speed of Mach 1 varies, based on temperature and air pressure. At sea level, on an average day, that is about 761 mph (speed of sound) Mach 89 would be an incredibly high speed- 89 times the speed of sound- about 67,729 miles per hour. I know of nothing that travels at that speed (light, of course, is faster) . Explosives don't travel that fast when detonating.
