Do you know relativity? I am not interested in discussing relativity
with someone who does not even know what the length contraction and
time dilation equations are.
The formula of the length contraction can be found at
http://en.wikipedia.org/wiki/Length_contraction
The equation for the time dilation can be found at
http://en.wikipedia.org/wiki/Time_dilation

The equation "Distance = Speed * Time" was taught in grade school. I
don't expect that you do not know that. Distance is a scaler
quantity. Distance is always positive. Please don't add a negative
sign to make it negative.

I think the problem was that you did not clearly define what your terms, x,
t etc meant. x is generally meant taken to mean a position in space along
the x-axis .. not a distance. using 'dx' or 's' might have been good idea
(dx meaning a difference between x values, and s a commonly used term for
displacement). Or maybe 'd' for distance (if you really do want
non-negative values).

Regardless, your equations for calculating the distances and times were
correct (to the accuracy you were using) in both cases .. but your
assumption that they should result in the same values was incorrect, as you
were calculating two quite different values (but confusingly using the same
letter 'x' in both cases).
