It is 3800 miles per hour.
Mach is a unit of speed based on the speed of sound (which varies with altitude and pressure). Mach 1 is the speed of sound, 340.29 m/sec or about 761.2 mph at sea level. Mach 2.5 would be 2.5 times as fast, or about 1900 mph.
Mach refers to the speed of sound in air. Typically about 750 mi/hr but it varies faster or slower with temperature from cold to hot respectively. Mach one is one times speed of sound. Mach 3 would be three times speed of sound.
Mach 0.82 equates to about 624.2 mph
216,000 miles per hour.
28 miles in 1 hour 38 minutes equates to an average speed of 17.14 miles per hour.
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 1 is 761.21 mph.Use this equation to convert Mach to miles per hour: mach x 761.21 = mph
1,903 miles per hour.
Mach 85 is 64,702.6 mph
Answer: 219,000 km/h = 136,080.291 mph
i think its 700 mph
Mach 82 is about 62,418.98 mph
Mach 2.34 is equal to 2445 KM/HR or 1548 MPH.
1294.04 miles per hour but it is dependent on temperature and atmospheric composition, Mach l is not a constant
mach 1 = 761.207 mph, so 761.207 * 0.791 = 602.115 mph
Mach is a unit of speed based on the speed of sound (which varies with altitude and pressure). Mach 1 is the speed of sound, 340.29 m/sec or about 761.2 mph at sea level. Mach 2.5 would be 2.5 times as fast, or about 1900 mph.
750*0.82=615 mph By the way, 1 mach is the speed of sound, which is 750 mph
