3m/s itself because in the case of a plane mirror the distance of the object to the mirror and the distance of the image to the mirror is always the same...Hence he will approach at the speed of 3m/s as there is no change in the distance

Same speed because the the magnification is +1 so if object size increases the image size also increases.
