How far apart are an object and an image formed by a 62 cm focal-length converging lens if the image is 2.75X larger than the object and is real?
Use the lens equation again. You should have memorized it by now.
Substitute 2.75 do for di and solve for image distance, di.
Distance from object to image = di + do = 3.75 di.
