Well you're only seeing this from the space perspective, you need to consider time also. Over time Achilles will be closer and closer to the tortoise, adding distances that are getting smaller, but you know that infinite sums can lead to a not infinite result. When you compare space over time (or velocity) of the 2 subjects you'll see that Achilles is going faster, and will eventually pass the tortoise.
