Srijato Bhattacharya from The Global Edge School, Kokapet Branch, Hyderabad
Class : Class 6
Here it is asking how far away boy Y would APPEAR to be in the mirror to boy X, as in, from boy X's perspective. Y is 12 m away from the MIRROR. He moves 5 m closer12-5=7This is where confusion may set in. A lot of people have added X's distance from the mirror(2 m)7 2=9Here, we are getting the total as 9 m.. However, it is also necessary to add 2 m for the reflected ray to travel to X so that he can see the image.9 2=11Hence, the answer is 11 m.
