<em><u>f</u></em><em><u>=</u></em>1/power
The approximate speed of sound in dry (0% humidity) air, in meters per second, at temperatures near 0 °C, can be calculated from
![c_{air} = (331.3+0.606 \upsilon)](https://tex.z-dn.net/?f=c_%7Bair%7D%20%3D%20%28331.3%2B0.606%20%5Cupsilon%29)
Here
Temperature in Celsius
Replacing with our values we have that
![\upsilon=58\° C](https://tex.z-dn.net/?f=%5Cupsilon%3D58%5C%C2%B0%20C)
![c_{air} = (331.3+0.606*58)](https://tex.z-dn.net/?f=c_%7Bair%7D%20%3D%20%28331.3%2B0.606%2A58%29)
![c_{air} = 366.1m/s](https://tex.z-dn.net/?f=c_%7Bair%7D%20%3D%20366.1m%2Fs)
Therefore the speed of sound in air at that temperature is 366.1m/s
