An ant runs from an ant-hill in a straight line so that its velocity is inversely proportional to the distance from the center of ant-hill. When the ant is at a point A at a distance 1m from the center of the hill, its velocity is 2 cm/s. Point B is at a distance of 2 m from the center of the anthill. The time taken by the ant to run from A to B is …….
a) 25s
b) 75s
c) 55s
d) 65s
