|Sound speed is 1235 km/h on 20C if speed is around that speed called sonic speed.
Below that Subsonic.
More then That Supersonic.
5 times more then that called hypersonic.

|The formula to find the speed of sound in air is as follows:
v = 331m/s + 0.6m/s/C * T.
v=350m/s or 1257 kmph almost equal to 1260kmph. can be said sonic.
