Hey mate here is ur answer. Hope it helps. Mark it as brainliest please
In fluid dynamics, the Mach number (M or Ma) (is a dimensionless quantity representing the ratio of flow velocity past a boundary to the local speed of sound

M is the Mach number,
u is the local flow velocity with respect to the boundaries (either internal, such as an object immersed in the flow, or external, like a channel), and
c is the speed of sound in the medium.
By definition, at Mach 1, the local flow velocity u is equal to the speed of sound. At Mach 0.65, u is 65% of the speed of sound (subsonic), and, at Mach 1.35, u is 35% faster than the speed of sound (supersonic).
