An ant runs from an ant-hill in a straight line so that its velocity is inversely proportional to the distance from the centre of the ant-hill. When the ant is at point A at a distance λ 1 = 1 m from the centre of the ant-hill, its velocity v1 = 2 cm/s, what time will it take ant to run from point A to point B, which is at a distance λ 2 = 2 m from the centre of the ant-hill ?
