A bird is sitting on the ground exactly in the middle of the pole and stone. The bird flies away towards the right in such a manner that its distance from the pole and the distance between the bird and the stone at any point of time is always equal. Calculate the distance between the bird and it's starting point after n seconds if the bird is covering 'd2'metres horizontally every second.
