Expert Answer
Since it is a plane mirror that person's image also move with the same velocity v towards him because in the plane mirror the object distance is equal to image distance.Hence if the man has moved a distance of x towards the mirror then the image also moved x distance towards the mirror.Thus the relative distance becomes equal to 2x giving a relative velocity if 2v.
