Solve the following question:

Question: The image of a tree on a 35 mm color slide is 1.6 mm high. It is to be projected onto a screen 5.0 m from the slide, and is to appear 482 mm high.

Part I: What focal length lens (in meters) is needed?

Part II: What is the distance in meters between the lens and the slide?

Part III: What is the magnification of the system?

Please show work I think I have the answer just not positive. Thank you.
