It really depends on what the sound is traveling through. Sound travels faster through hard things, in fact, I hear it travels 22 times faster through brick than through air. If you are talking room temperature at a few thousand feet above sea level it should travel at about 775 miles per hour, (1,240 kilometers per hour.)

no from what i have learned light travels faster then sound
Solids
1000 feet
3400mph
I believe you mean "why does it matter how fast sound can travel?" There are many reasons for why it matters to know how fast sound travels. it can help with determining the distance of a lightning storm, tuning instruments, and is helpful with ballistics. -Tychusfindlay919

No matter what you do to either of them, light is always going to travel at least several hundred times as fast as sound, and most generally about 800 thousand times as fast as sound. Sound will never travel faster than light, in any situation.
They both travel in the form of waves, and they both travel very fast.
Sound travels faster in solids because the particles in a solid are closer together and tightly connected, allowing vibrations to pass quickly from one particle to another. This direct and efficient transfer of energy between particles enables sound waves to move rapidly through a solid medium.
It is called fast travel
