A thin converging lens with focal length...

A thin converging lens with focal length `f = 25 cm` projects the image of an object on a screen removed from the lens by a distance `l == 5.0 m`. Then the screen was draws closer to the lens by a distance `Delta l = 18 cm`. By what distance should the object be shifted for its image to become sharp again ?
