The speed of sound in dry air at room temperature (around 20 degrees Celsius or 68 degrees Fahrenheit) is approximately 343 meters per second (m/s) or 1,125 feet per second (ft/s). However, the speed of sound can vary depending on factors such as temperature, humidity, and the medium through which it travels.
In general, sound travels faster through denser and warmer mediums. For example, sound travels faster in water (approximately 1,480 m/s or 4,850 ft/s) and even faster in solids like steel or rock. The speed of sound is an important parameter in fields like acoustics, aviation, and physics.
