As temperature falls during the night the speed of sound slows slightly. However the apparent clarity of the sound often goes up as there are fewer competing sounds (traffic noise falls off, no lawn mowers working, etc). This may be interpreted as the sound being closer or coming to you faster.

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.
