An ant runs from an ant-hill in a straight line sothat its velocity is inversely proportional to thedistance from the center of ant-hill. When the antis at a point A at a distance 1 m from the centerof the hill, its velocity is 2 cm/s. Point B is at adistance of 2 m from the center of the ant-hill. Thetime taken by the ant to run from A to B is(1) 25 s(3) 55 s(2) 75 s(4) 65 s
