Answer:
3 cm/s
Explanation:
if the object is approaching the mirror with velocity u velocity of the image will be same as that of object because at any moment the distance of the image from the mirror is same as the distance of the object form the mirror.
So, Relative velocity of the object with respect to the image will be 2u because if the object is moving toward mirror , its direction is taken as positive and image will move towards in negative direction .
