Obtain over what distance must the lens be movable

To focus a camera on objects at different distances, the converging lens is moved toward or away from the film, therefore a sharp image always falls on the film. A camera with a telephoto lens (f = 210.0 millimeter) is to be focused on an object placed first at a distance of 3.5 meter and then at 54 meter. Find over what distance must the lens be movable?
