Solution
A person 1 m in front of a plane mirror seems to be 2 m away from his image.
Explanation:
Object distance and image distance are the same as those of a plane mirror. The image of a person 1 m in front of a mirror is 1 m back to the mirror. Hence, the image is 1 + 1 = 2 m away from the person.
