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.
How fast is 0.85 mach?
Mach 1 is 761.21 mph.Use this equation to convert Mach to miles per hour: mach x 761.21 = mph
About 25.3 miles per hour.
Mach 2.34 is equal to 2445 KM/HR or 1548 MPH.
2.5 miles per hour equates to 4.02 kilometers 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.
