Mach 1 is the speed of sound about 760mph.
Mach 1 per second is 230,281,663 feet per second.
Mach 1 (or the speed of sound) is 1,225km per hour Mach 75 is there for 91,875 km/h
Close! Actually, Mach-1 is the speed of sound. anything above Mach-1 (Mach-(1-5)) is supersonic, all the way up to Mach-5, at which point an object is called "Hypersonic". Sometimes speeds above Mach-10 are referred to as "High-Hypersonic". So, a jet moving at Mach-1 wouldn't actually be traveling FASTER than sound, it would be traveling AS FAST as sound.
The way you calculate mach into mph, is you type it into the calculator and it will tell you the answer! Now go do it....
Yes
In fluid dynamics, the Mach number) is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound. Mach 1 is equal to 340.29 m / s
mach 1 = 761.207 mph, so 761.207 * 0.791 = 602.115 mph
Mach 1.7 is equal to about 1294 mph.
750*0.82=615 mph By the way, 1 mach is the speed of sound, which is 750 mph
There is no finite answer to this, since the term Mach (the speed of sound through air or water) changes based on the temperature of the air itself. In 60 deg F air at sea level, Mach 1 is 761mph. In dry air at 68 deg F, mach 1 is 768 mph. Mach 1.4 is 1.4 x these speeds. Usually Mach speeds are used for objects travelling in air, but not always. Mach 1 in water is 4.3 times faster than air and Mach 1 in iron is 15 times faster than air.
Frantisek Mach is 6' 1 1/2".
Mach is the coefficient of the speed of sound, so Mach 1 means you are travelling at 1 x the speed of sound.
The mach number is the speed, compared to the speed of sound in air. Thus, mach 1 is the speed of sound, mach 2 is twice (2 times) the speed of sound, mach 3 is 3 times the speed of sound, etc.
Mach 2.34 is equal to 2445 KM/HR or 1548 MPH.
Mach 1 is about 762 mph, so mach 20 is about 15,240mph.

There is no plural for the noun 'mach'; the different levels of mach are usually shown by a numeral for various speeds, such as mach 1 or mach 2.
