You stand 3.5 m in front of a large mirror, and your little sister stands 2.0 m directly in front of you. At what distance should you focus your camera if you want to take a picture of your sister in the mirror?

Answer:

D = 3.5 m to mirror

d = 1.50 m from mirror to sister

Total distance from camera to sister = d + D = 5.0 m
