Now,distance between the boy and his image is 7 +7 i e 14 meters So,the image moved to him by (20 −14) or 6 meters Alternatively, From the above discussion,clearly, v + u = x (let)= 2u So, x = 2u Or, dx dt = 2 du dt It means velocity of image should be twice than that of man's velocity,so if the man moves by 3m then the image will move to
