When I calculated your question i got 2,464 MPH as the answer,I might be wrong but I don't think so.(if you want to know how I got that I multiplied 770 by 3.2.)

Mach 1 is 761.21 mph.Use this equation to convert Mach to miles per hour: mach x 761.21 = mph
Mach 2.
Ok, let's figure this one out: Assume mach speed is 1,010 feet per second, we could travel 689 miles in one hour. (1010 ft * 60sec *60min) / 5,280 ft = 689 mph rounded. Therefore, 0.81 of mach should be 558.09 mph
A Mach number is a dimensionless quantity representing the ratio of speed of an object moving through a fluid and the local speed of sound. A Mach number varies by the composition of the surrounding medium and also by local conditions, especially temperature and pressure. As such, it cannot be quantified to a particular speed.As a very rough estimate, use 760 mph.
The Mach number for speed is a function of how fast an object is going relative to the speed of sound in that medium (which can vary). The speed of sound at sea level is around 768 mph, so Mach 3.3 at around this level will be 768 x 3.3 = 2534 mph
Mach 1 is the speed of sound. 768 miles per hr. Mach 2 is twice that & so on.
Mach 1 is 761.21 mph.Use this equation to convert Mach to miles per hour: mach x 761.21 = mph
Mach velocities are all relative to the speed of sound in that gas, at that density. Mach 1 = the speed of sound. Mach 2 = twice the speed of sound. It does not have an invariant conversion into miles per minute.
2,608.72 miles per hour.
The speed of sound is around 760 miles per hour = Mach 1. So Mach 4 is 4*760 = 3040 mph.
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 24 is roughly equal 18,264 miles per hour. Mach is a term used to describe the ration of the speed of an object to the speed of sound. The speed of sound, at sea level, is roughly 761 mph. Mach 24 means that the ration of the speed of an object to the speed of sound is 24, meaning 24 times the speed of sound. Thus, at sea level, an object travelling at mach 24 is travelling at 24 times 761mph, which is 18,264 miles per hour.
Mach 10 is equivalent to 3,402.9 meters per second. It is about 7,000 miles per hour. At Mach 10, an aircraft could circumnavigate the earth in less than four hours. The Mach number is a measure of how fast an object is travelling relative to the speed of sound. The Mach number is calculated by dividing the speed of an object by the speed of sound. Speed of sound is about 760mph
The absolute top speed remains classified. Officially "in excess of Mach 3" Probably closer to Mach 3.5 - 3.8
Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.
2283.6211 miles per hour is considered as mach 3. To be able to reach Mach 1 is to go 761.207 miles per hour. It is used to measure the speed of aircraft and rocketry.
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
