Question

Atul is standing 10m away from a plane mirror and Raju is standing 5m behind Atul. Now
if Atul walks 5m towards the mirror. What is the distance between himself and the image of Raju? ​

Answer 1

Answer:

10 m

Explanation:

Because atul is on 5m distance from raju the he moves 5m towards mirror and then 5+5=10m

Answer 2

Explanation:

Atul is standing 10 M away from the mirror

Raju is 5m behind Atul

So,

Atul-10 m from mirror, Raju-15m from mirror(as Atul is 10m and Raju is 5m behind Atul so..10+5m)

2nd Case
Atul Walks 5m towards(coming through- the distance is getting covered so we have to subtract)
So,

Atul=10m-5m=5m(Distance from Atul and his mirror)
Raju's Image is 30 cm away from him as,
Image=*2

15*2=30, Now Diffrence 30m-5m=25m

Answer:
25m
