Answer: The speed of image will be 60m/s
Explanation:
The object moves at the speed of 20m/s and the mirror also moves at the speed of 20 m/s the velocity of image will be (vel. Of object+ 2*vel. Of mirror) as the image of object wil also move twice with respect to object as mirror and object both are moving . Thus 20 + 2*20= 60m/s .
Thus 60m/s will be speed of image.
