Answer 2

Answer:

Explanation:

Let say the object is placed at origin.

Let the say the distance of object from mirror is x.

So the distance of image from mirror is x.

And distance between object and image is 2x

Now in 1 hr mirror moved by 4km.

The distance of object from mirror is x−4.

Distance of image from mirror is (x−4)

Distance between object and image is x−4+x−4=2x−8

Initially they were separated by 2x distance and now 2x−8

So distance traveled by image in 1 sec is =2x−(2x−8)=8

Speed of image is 8km/hr.
