The absolute top speed remains classified. Officially "in excess of Mach 3" Probably closer to Mach 3.5 - 3.8
3 planets.
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.
About 3% and only 1% is able to be drank. The rest is frozen in ice caps and glaciers.
The Concorde aircraft cruised at Mach 2 at about 19,000 m (62,000 ft), and the SR-71 cruised at Mach 3 at 26,000 m (85,000 ft), all within the stratosphere.
Mach 3 = 2283.6211 mph
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 3 is 2283.6211 mph because Mach 1 equals 761.207033 mph.

Mach 3.6 = 2,740.34 mph
Mach 3 - 2012 was released on: USA: April 2012
Elena Bog was born on April 3, 1941, in Bessarabia, USSR.
from the crossword puzzle in social studies or science
Mach 3 means flying three times the faster than sound. Speed of sound at an usual temperature is 346m/s. This means Mach 3 is about 1 km/s. That is 3600kmph. That is 2250 mph.2283.59 mph
well the sr-71 exeeds mach 3(a little faster) or the space shuttle(not a jet)
It can fly at 1.75 mach with out after burners and with after burners reaches about mach 3.
