Initial distance of student from mirror: 1.5 m

Final distance of student from mirror: 1.5 m + 0.5 m = 2.0 m

Distance of image from mirror when student is 1.5m away: 1.5 m

Distance of image from mirror when student is 2.0m away: 1.5 m

Change in distance of image from mirror: 1.5 m - 1.5 m = 0 m

Working: The distance of the image from the mirror remains the same as the distance of the object from the mirror for a plane mirror. Therefore, even though the student moves further away, the image remains at the same distance from the mirror.
