dist of Child and its image in the mirror will always be equal.
so,
speed of child wrt the mirror = speed of image of the child wrt the mirror.
so, speed of the image wrt mirror = 5 m/s
and speed of the image wrt the child = 10 m/s
so,
speed of child wrt the mirror = speed of image of the child wrt the mirror.
so, speed of the image wrt mirror = 5 m/s
and speed of the image wrt the child = 10 m/s
