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.

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.
because the atoms in solid are compact it helps sound to travel fast
there is no air in a vaccum. and sound needs air for the sound waves to travel through.
Sound cannot travel through a vacuum, such as in outer space. "Sound" refers to waves of compression which travel through matter. When there is no matter, there can be no such waves, and therefore no sound.
Sound cannot travel through a vacuum.
It doesn't matter. If you fast travel he will travel there with you. So if you want summary it doesn't matter.
Yes. Sound is produced by vibrating matter, such as a string or arts of the inner ear, so it cannot travel if there is no matter to vibrate.
Sound waves can travel through any matter- liquid, gas or solids. The denser the matter, the faster the sound travels. It cannot travel through vacuum- a vacuum is an absence of matter.
Sound travels by vibrating through matter (solid, liquid, gas) A vacuum is the absence of matter and with out matter there is nothing for sound to travel through
in solid state of matter
yes., sound can travel through plasma because it is matter.
