Not quite...its based on the speed of light (which is a universal
constant), not an individual's speed.
speed of light = c = 3.00x10^8 m/s
3.00x10^8 m
c = -----------
1 s
1 s = 3.00x10^8 m
This is why superlarge 'distances' are measured in light-'years',
and why smaller 'distances' are measured in 'distance' units.
Its just more convenient for that purpose.
You could say the distance/time from Dallas to Abilene is either
182.3 miles or 0.000979 sec.
Try this out...ask someone how far it is from where your at to
a store across town. Quite a few people will respond by saying
something like, "about 5 minutes thataway". The concept of
'distance' and 'time' are quite fuzzy. (of course the above axample
isn't based on the speed of light, otherwise that store is a looong
way away).
OK, I'll stop now, enough physics for 2.592x10^13 meters...
err... I mean, one day... :-)
