What is the speed of sound in air at room temperature

The speed of sound in air at room temperature (20°C) is approximately 343 m/s.  This speed depends on the temperature and medium.  As temperature increases, the speed of sound also increases.  This is because the molecules in the air move faster, allowing sound waves to propagate more quickly.
