Understand the concept of image formation in a plane mirror: The image formed by a plane mirror is virtual, upright, and the same size as the object. The distance from the object to the mirror is equal to the distance from the mirror to the image.
Identify the given information: You are standing 3 feet from the mirror.
Apply the mirror image distance principle: Since the distance from you to the mirror is 3 feet, the distance from the mirror to your image is also 3 feet.
Calculate the total distance from you to your image: Add the distance from you to the mirror and the distance from the mirror to your image. This is 3 feet + 3 feet.
Conclude the total distance: The total distance from you to your image is 6 feet.
