The
speed of sound
varies depending on the temperature, pressure, and density of the medium through which the sound waves travel. For dry air at sea level at 68° F, the speed of sound is 767 miles per hour, or 1235 km/h
en.wikipedia.org/wiki/Speed_of_sound

The speed of sound is the distance travelled per unit time by a sound wave as it
propagates through an elastic medium. In dry air at 20 °C (68 °F), the speed of
sound is 1,130 feet per sec...

To calculate the speed of sound in dry air at sea level, use the following formula:
V = 331.4 + 0.6Tc. V = velocity (m/s), T<sup>c</sup> = temperature in Celsius.
