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

Here's a breakdown:

* In air: At standard temperature and pressure (20°C or 68°F), the speed of sound is about 343 meters per second (767 miles per hour).

* In water: Sound travels much faster in water than in air. At room temperature, it's around 1,482 meters per second (3,315 miles per hour).

* In solids: Sound travels even faster in solids, like steel. In steel, it can travel at about 5,960 meters per second (13,300 miles per hour).

Factors that affect the speed of sound:

* Temperature: Sound travels faster in warmer mediums.

* Density: Sound travels faster in denser mediums.

* Elasticity: Sound travels faster in more elastic mediums.
