Answer:
Light travels faster than sound because sound waves can only travel as waves of pressure in a medium, whereas electromagnetic waves, of which light is made, move on their own even through vacuum.

Light and sound are very different. Sound is actually a mechanical disturbance through air or another medium. Sound always needs a medium to travel through, and the type of medium determines its speed.
Light doesn’t need a medium to travel.
The speed of sound through air is about 340 meters per second. It’s faster through water, and it’s even faster through steel. Light will travel through a vacuum at 300 million meters per second
This is why Light travels faster than sound.
