sound is a vibration, a wave that travels in an elastic medium. the speed of sound describes the distance such a wave travels for a given amount of sound

in dry air at 21°c (70°f), the speed of sound is 344 m/s (1230 km/h, or 770 miles, or 1130 ft/s). although the speed of sound usually refers specifically to air, it can be measured with almost any substance. sound travels much faster in liquids and non-porous solids than in air.

the most important factor affecting the speed of sound in the earth's atmosphere is temperature
