The speed of sound isn't a single, fixed number. It varies depending on the medium through which it travels.

Here are some common examples:

* Air: Approximately 343 meters per second (767 miles per hour) at 20 degrees Celsius (68 degrees Fahrenheit).

* Water: Approximately 1,482 meters per second (3,320 miles per hour) at 20 degrees Celsius.

* Steel: Approximately 5,960 meters per second (13,300 miles per hour).

Factors that affect the speed of sound:

* Temperature: Sound travels faster in warmer temperatures.

* Density: Sound travels faster in denser mediums.

* Humidity: Sound travels slightly faster in humid air.
