Explanation / Answer
Use the lens formula: 1/p + 1/q = 1/f P is the object distance. It is positive for real objects infront of the mirror. It is negative for virtual objectsbehind the mirror. Q is the image distance. It is positive for real images infront of the mirror. It is negative for virtual images behindthe mirror. F is the focal point. It is positive for concave lenses whichinvert images. It is negative for convex lenses which haveupright images. From the given information we know that the lens is convex and thatthe objects are in front of the lens. Plug the numbers intothe equation and solve for Q. Then determine if the image isreal or virtual.
