image on the plain mirror is proportioal to each other i mean the distance of the person standing in front of a mirror is the same as the distance of the person that you are seeing on the mirror which tend to make it look like your orther image is at the back of the mirror so there
6 of your real image = 6 of that fake image that appear coming from the mirror (screen)
6 + 6 = 12 cm
the same thing apply to the speed
