To determine the flight time for 6,600 miles at a speed of 0.85 Mach, we first convert Mach to a speed in miles per hour. At 44,000 feet, 0.85 Mach is approximately 565 mph. Dividing the distance (6,600 miles) by the speed (565 mph) gives a flight time of about 11.7 hours. Therefore, it would take approximately 11 hours and 42 minutes to complete the flight.
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.
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.
Maximum speed: Mach 0.96Operating speed: Mach 0.89

To mach for you if you cant spell it.
Mach 2.
The homophone for "mach" is "mock."
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 0.85 would be approx 646 mph.
