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 343 metres per second ... For example, (as noted above), sound travels at 343 m/s in air; it travels at 1,484 m/s in water (4.3 times as fast as in air); and at  ...
