A converging lens (f = 27.5 cm) is used to project an image of an object onto a screen. The object and the screen are 113 cm apart, and between them the lens can be placed at either of two locations. Find the two object distances. (Enter your answers from smallest to largest.)
I have tried this problem, but I don't even know where to begin, I have tried just splitting the distance between the two and using that, but nothing seems to work, thanks for any help!
