What is the speed of a supersonic jet?

A supersonic jet typically travels at speeds greater than the speed of sound, which is approximately 1,125 feet per second (343 meters per second) at sea level. This translates to speeds exceeding Mach 1, with many supersonic jets reaching speeds between Mach 1.5 and Mach 3. For example, the Concorde operated around Mach 2.04, allowing it to significantly reduce flight times compared to subsonic aircraft.
