An older camera has a lens with a focal length of 55 mm and uses 36-mm-wide film. Using this camera, a photographer takes a picture of the Golden Gate Bridge that completely spans the width of the film. Now he wants to take a picture of the bridge using his digital camera with its 16-mm-wide CCD detector. What focal length should this camera's lens have for the image of the bridge to cover the entire detector?
