Distance between David and the image will be 6m
princessdarpan:
see
the distance between the object and the mirror and the distance between the mirror and the image is constant
so if David's first distance between the mirror and him was 4m, then the distance between his image and the mirror would also be 4m
total distance = 4+4=8
now since David moves 1 m closer, the distance between him and the mirror is 6m, so is the distance between his image and the mirror
now total distance = 3+3 = 6m
hence proved
hope this helps
ye
thanks
