The distance between the object and mirror is 15 mm. The distance between the image and mirror is 15 mm. Therefore, the distance between the image and object is 15 mm plus 15 mm which equals 30 mm.
With plane mirrors, the distance of the image from a mirror is identical to the object from the mirror. In this case, the image would be located 15 mm behind the plane mirror.
The distance of the image from the mirror is equal to the distance of the object from the mirror, irrespective of its height. So the image of that object should be 15mm from the mirror.
The virtual image appears to be 15 millimeters behind the mirror.
The height of the object makes no difference.

Put a mirror in front of it.
Mirror reflects light from an object and that means that it reflects light from the right side of an object to the right side of a mirror and light form the left side of an object to the left side of a mirror. The picture that is created in a mirror is actually a reflection of an object that is in front of a mirror and therefore it looks reverse.
It's a virtual reflection of the object which appears as an image as much behind the mirror as the distance of the object in front.
Here is a description of image formation in a concave mirror: if the object is beyond the center of curvature (F), the image formed is real and upside down; if the object is very near to the concave mirror, the image forms behind the mirror. It is virtual, upright, and bigger in size. Here is a description of image formation in a convex mirror: a convex mirror always produces a virtual, upright, and smaller image of the object at any distance in front of it. The image is located behind the mirror.

The answer is 15 millimeters behind the mirror, and the distance from the actual object to the image is 30 millimeters. Plane mirrors have a flat focus that places the image as far behind the mirror as you are in front of it.

real reflection of the object in front of it at a time.
Here is a description of image formation in a concave mirror: if the object is beyond the center of curvature (F), the image formed is real and upside down; if the object is very near to the concave mirror, the image forms behind the mirror. It is virtual, upright, and bigger in size.
