The distance from observer is 52 m
Explanation:
The object is placed in front of mirror at a distance of 50 m .
In case of mirror , the image is formed as far behind the mirror as the object is in front of it .
Thus the image will be formed at a distance of 50 m behind the mirror .
As the observer is 2 m in front of the mirror
Thus the distance between observer and image is
50 + 2 = 52 m

Answer:
54m
Explanation:
total distance of chart from mirror is 50m+2m=52m so image distance of chart from plane mirror will also be 52m.
now our eyes are 2m away from plane mirror.
total distance of chart image to our eyes = 52+2m=54m
