The Mach number for the speed of an object travelling through a particular medium is the ratio of the object's speed relative to the speed of sound through the same medium. The speed of sound through any medium depends on the nature and density of the medium and, as a result, so does the Mach number. In air, the Mach ratio is mostly dependent on temperature and humidity, less so on altitude.
Generally, Mach 1 (in air, at standard sea level conditions, and at 15 deg C) is approx 760 mph. So Mach 1.8 would be approx 1370 mph.
Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.
Rounded to two decimal places, Mach 1 is equal to 761.21 miles per hour. Multiplying this by 1.6 gives us 1217.38 miles per hour.Converting 1217.38 miles per hour to metres per second gives us 544.46 metres per second.
Mach 10 = 7,612.07 mph
Mach 2.2 refers to 2.2 times the speed of sound. The speed of sound is variable, depending on pressure and temperature. The speed of sound on a standard day at sea level is approximately 762 miles per hour. Mach 2.2 on a standard day at sea level would be approximately 1676.4 miles per hour, or 27.94 miles per minute, or approximately half a mile per second.
It is81.25 miles per hour
Mach 19 is 14,462,934 miles per an hour
Mach ten is equal to 7,612 miles per hour.
Mach 6 is about 4,567 mph
2664.2 Miles Per Hour
How fast is 0.85 mach?
1,150.9 miles per hour.
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 10 is equal to 7,612.71 miles per hour (mph) at standard atmospheric conditions.
Mach 1 = 761.207051 Miles Per Hour Mach 2 = 1,522.4141 Miles Per Hour Mach 3 = 2,283.62115 Miles Per Hour Mach 4 = 3,044.8282 Miles Per Hour http://en.wikipedia.org/wiki/Mach_number
Mach 9 would be approximately 9 times the speed of sound, or 6,192 miles per hour.
MACH 1.8 (1,190 Miles per hour)
It's speed in miles per hour is 1294.0519864 mph.
