If Achilles, without his tortoise, covers $\frac1{2^n}$ meters in $\frac1{5^n}$ seconds for each $n$, does he reach $2$ meters in $\frac54$ seconds?

I am Achilles II and, on a straight line, I start running really fast:

  • The first $1$ meter I cover in $1$ second.

  • The next $\frac{1}{2}$ meters, in $\frac{1}{5}$ seconds.

  • The next $\frac{1}{2^2}$ meters, in $\frac{1}{5^2}$ seconds.

  • And so on. That is, for $n=1, 2, 3, \ldots$, I cover the each successive $\frac{1}{2^n}$ meters in $\frac{1}{5^n}$ seconds.

So, as the total time I run $$t = 1 + \frac{1}{5} + \frac{1}{5^2} + \frac{1}{5^3} + \cdots$$
tends to $\frac{5}{4}$, the total distance I cover $$d = 1 + \frac{1}{2} + \frac{1}{2^2} + \frac{1}{2^3} + \cdots$$ tends to $2$.

Now, my velocity is $v = (\frac{1}{2^n})/(\frac{1}{5^n}) = (\frac{5}{2})^n$. So, as $t$ tends to $\frac{5}{4}$, $v$ increases and tends to infinity.

I also assume that I cannot “jump” in space. I move only in straight lines.

The question is:

If I can move in this way, does it follow that at time $t=\frac{5}{4}$ I am at distance $d=2$?
