Two thin lens (the first with a primary focal length of -0.1667m) are separated by a distance 'd'. An object is placed 30 cm to the left of the first lens. After light is refracted through both lenses, an image is formed that is 1.92x the size of the original object and located 26.92cm to the right of the second lens. What is the separation distance 'd' between the two lenses?
