## The Long Walk

A few months ago, we had a running dog. This month it's a walking fly.

An elastic strip of length 1m is attached to a wall and the back of a car. A fly starts at the wall and crawls on the strip towards the car, which at the same time drives away from the wall at a speed of 1m/s.

Assuming that the strip can be stretched infinitely long, will the fly ever reach the back of the car?
