the image between the mirror and the object is 12 cm as the distance between real image and virtual is 24cm both images are same distance from the mirror so the actual distance half of the total distance.

Answer:
For plane mirrors, the object distance (often represented by the symbol do) is equal to the image distance . That is, the image is the same distance behind the mirror as the object is in front of the mirror.
For example, if we stand at a distance of 2 meters from a plane mirror, we must focus at a location 2 meters behind the mirror in order to view our image.
In this case, the distance between the object and its image formed by a plane mirror appears to be 24 cm. So, the object distance will be 24 / 2 = 12 cm.
Hence, the distance between the mirror and the object is 12 cm.
