For a flat mirror, the object distance is equal to the image distance. Therefore, the image would be 28 m behind the mirror. So you are 1.4 + 28 = 29.4 m from the mirror. If the mirror were flat, the image height would be the same as object height = 1.5 m.

Is it true that the objects in the mirror are closer than they appear?
