Question

what is the speed of sound

Answer 1

The speed of sound in an ideal gas depends only on its temperature and composition. The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior.

Answer 2

I hope it will help you ........

The speed of sound is the distance travelled per unit time.....
 In dry air at 0 °C, the speed of sound is 331.2 metres per second. ... 
Sound can travel in air at approximately 332 metres per second. This is fast but not nearly as fast as light which travels at 300 000 kilometres per second. This difference in speeds enables us to appreciate that sound does take time to travel.
