the speed of sound and light
the speed of light = 299 792 458 m / s according to a

The website
Speed of Light examines this further and states that in "a vacuum, light always travels at a speed of 299,792,458 meters per second, no matter how its speed is measured. is 299,792,458 meters per second, no matter how its speed is measured." Basically this is accepted fact and is confirmed with different details examined at
The Speed of Light - A Limit on Principle?.
speed of sound at sea level = 340.29 m / s according to a
Google search.
There are formulae available to calculate the speed at which sound travels through certain gasses
