Usha wants to take a picture of her own image in a plane mirror. At what distance should the camera lens be focussed if it is positioned 2.3 m in front of the mirror?

is it 2.3*2 ?... 4.6m ??

In mirror the object distance = image distance. Find the distance between Usha and her image and focus the camera.

so is it 4.6m?, since distance in the mirror is 2.3 m and image distance is also 2.3m
