| You and I have a different interpretation of what those answers mean. The
| numbers I gave were derived from Einstein's special theory of relativity.

The numbers you gave are the physical speeds.
If you use time dilation for such numbers you are just being silly.
and will come up with incorrect speeds since
time dilation is a simple clock malfunction, not a physical reality
change.
The standard of time measurement is based upon a stationery
frame on Earth, using a moving frame relative to Earth frame of reference
is just plain wrong and not standard anymore at all.
:)




Speed in relativity is still the distance traveled divided by the elapsed
time. But to "use time dilation" is silly because dividing a distance
traveled as measured in one frame by an elapsed time as measured in a
different frame is meaningless. If you're the one making the measurement,
then use the distance you measure and the time you measure. If I'm the
one making the measurement then I'll use the distance I measure and the
time that I measure.
