Answer 2

A supersonic speed has a Mach number ranging from 1.2 to 5. Supersonic speed tells us that an object's rate of travel is faster than the speed of sound. The Mach number is a dimensionless ratio between velocity and the local speed of sound for an incompressible flow in liquids and gases. It is determined by the equation M = u/c where u is the local flow velocity and c is speed of sound in the medium.
