Say what now? Distance Traveled= Rate x Time. If the rate is zero,

Not if you use the D=RT formula, it is 'undefined' when either R or T
is zero (I did *not* say approaching zero).

Complete nonsense. If R = 0, then D = 0T = zero. If T = 0, then D = 0R =
zero.

There's no division in D= RT. That's multiplication.

If the rate is zero by stipulating that it is so, and the distance is
zero by multiplication using Ohm's Law, the time must be infinite since
we aren't moving.

That is incorrect. In the equation D = RT, if D and R are both zero, T can --
and must -- be any finite number (e.g. if T = 5 and R = 0, then D = RT = 0 *
5 = 0). The one thing T *cannot* be is infinite: zero times "infinity" is
what we call in mathematics an "indeterminate form" that cannot be evaluated
algebraically.

Right, so we're left with an answer of undefined.

So, if the T is as you state 'any finite number' there must be a rate
of D/T and if that finite number T is zero we're back at division by
zero and if that finite number T is not zero we're back at some
positive or negative rate which is a contradiction of your original
premise of R being zero.

Since time is T=D/R the time is undefined by division
by zero

Correct, but not relevant to the equation D = RT which is *not* the same
thing:

-- D = RT is defined for all real values of all three variables
-- T = D / R is defined for all real values of D and T, and non-zero values
of R

Okay, you got me there. I was treating D=RT as a formula not just as an
equation. My mistake. E=MC^2 so if C=0 E=0 and M doesn't matter. Got it
now, sorry for wasting your time.
