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.
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).
Surface-to-air missiles typically travel at speeds between Mach 2 to Mach 5, which is approximately 1,534 to 3,806 miles per hour (2,470 to 6,126 kilometers per hour). The speed can vary depending on the specific type of missile and its intended target.
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.
