Let's do the math. We know that the speed of sound, also known as mach, is 1,010 feet per second. Six times that equals 6,060 feet per second. So, if we are going 6,060 feet in 1 second, that mean in one hour we can go 21,816,000 feet in one hour. (60*60*6060). Now divide this by 5,280 feet (1 mile) and we have 4,132 MPH.
Mach 7 is approximately 7 times the speed of sound, which is around 5,370 miles per hour or 8,660 kilometers per hour. At Mach 7, an object would be traveling at about 8,660 miles per hour or 13,920 kilometers per hour.
The Mach number is simply the speed of an object divided by the speed of sound. While the speed of sound varies according to a number of factors, at sea level on a standard day (15C and 29.92 inches) it is 761.2 mph. Mach 6, then, would be 6 times that speed, or 4567.2 mph (at sea level on a standard day).
It is also important to note the velocity changes with the altitude. So, at 20 miles altitude (a reasonable altitude for something going mach 6), the speed for mach 1 is 683.7 mph, resulting in 4102.2 mph when multiplied by 6.

Scramjets can reach speeds up to Mach 15 (15 times the speed of sound) which is around 11,500 mph (18,500 km/h). They are designed to operate efficiently at hypersonic speeds, typically around Mach 5 or higher.
Mach one is the speed of sound, which is about 761.2 miles per hour (340.3 meters per second). Mach two is twice the speed of sound, which is about 1,522.4 miles per hour (680.6 meters per second).
"Mach" isn't a force.
Mach 8.5 is approximately 6,497 miles per hour (10,462 kilometers per hour) in standard atmospheric conditions at sea level. It is around 8.5 times the speed of sound, which is 767 mph or 1,235 km/h at sea level.
