I like this notation.

I'm not sure, however, why t = x / v should involve lots of computation.
If length, velocity, time are implemented as I proposed in my other
email, x would contain the length in meters, v the velocity in meters
per second, and time the time in seconds.  Thus, one division.  The
conversions into SI units would be done in the assignments above.
