Re: Missing information

Speed of light in air is 299,700 km/s (~3*10^8 m/s) very close to the speed of light in a vacuum so not sure where you get the 3.10^9 from (which according to my calculator is 26439.6)

Rule of thumb - light goes at about 1ft per nanosecond or more accurately 30cm/ns. Resolving to 1ns isn't too bad but better is easily achievable.
