The speed of a body that has Mach number more than 1 is-

Supersonic

Subsonic

300 m/s

about 10 m/s

Explanation:

The term supersonic is used to describe a speed that is over the speed of sound (Mach 1). ... Speeds where only some parts of the air around an object (like the propeller) reach supersonic speeds are called transonic (normally somewhere between Mach 0.8 and Mach 1.2). Whips have operated supersonically for many centuries.
