How many feet per second is hypersonic?
Hypersonic is defined as five times the speed of sound. The speed of sound is about 750 mph* or about 1000 feet per second*. A mile is 5280 feet, so the threshold for hypersonic flight is about a mile per second.
How fast is a bullet in Mach?
To put this into context, the average bullet travels about 1,700 miles per hour. Mach 1 is about 767 miles per hour. A railgun projectile will travel at Mach 6 – that’s nearly three times faster than the typical bullet.
