Answer:
6m

When the distance between the mirror and the image is 4m the total distance between object and image is twice of that that is 8m.So if he moves towards the mirror by 1m the image to will move by 1m. Then the distance between David and his image will be :
distance between david and mirror(3m) + distance between image and mirror(3m)= 3+3 = 6m
