Answer:13.2,41.4,82.8 ft
Explanation:
Given Person is 6.60 ft from the left hand side mirror
Since the focal length of plane mirror is infinity therefore image and object are equidistant from mirror
Distance of first image on left mirror is
i.e. image is 13.2 ft away from object
Second image
Now the right mirror forms the image of object at distance of 14.1 ft right from right mirror so its image is formed in left mirror at a distance of 34.8 from left mirror
so image distance from person is
Third image now form image of second image is formed on right mirror at a distance of 55.5 right from right mirror
and its mirror image is formed on left mirror at a distance of 76.2 left
from left mirror
