Ant on a rubber rope the end of each second. Let formula_16 be the proportion of the distance from the starting-point to the target-point which the ant has covered at time "t". So formula_17. In the first second the ant travels distance formula_18, which is formula_19 of the distance from the starting-point to the target-point (which is formula_20 throughout the first second). When the rope stretches suddenly and instantaneously, formula_16 remains unchanged, because the ant moves along with the rubber where it is at that moment. So formula_22. In the next second the ant travels distance formula_18 again, which is formula_24 of the distance from
