Answer:
The speed has a weak dependence on frequency and pressure in ordinary air, deviating slightly from ideal behavior. In colloquial speech speed of sound refers to the speed of sound waves in air.
Explanation:
Sound measurements
Sound pressure p, SPL,LPA
Particle velocity v, SVL
Particle displacement δ
Sound intensity I, SIL
The sound velocity through a given material is the distance that the sound energy will propagate in that material in a given time, and it is a function of material density, acoustic impedance and temperature. Since sound velocities are relatively high, most values are given in meters or feet per second.

Answer:
At 20 °C (68 °F), the speed of sound in air is about 343 metres per second (1,235 km/h; 1,125 ft/s; 767 mph; 667 kn), or a kilometre in 2.9 s or a mile in 4.7 s. speed of sound
