Question

1. Two boys are standing in front of a plane mirror as
shown in the given figure. If boy Y walks 5 m towards
boy X, then how far away would boy Y appear to be in
the mirror to boy X?​

Answer 1

Answer:

9 m

Explanation:

Because from 12 m he walked towards X boy and the X boy was already 2m far from the mirror so now you all can calculate! Thank you hope so this will help you

Answer 2

Boy Y appears 11m far in the mirror from Boy X.

Given:

Boy X's distance from the mirror = 2m

Boy Y's distance from boy X = 12 m

Distance boy Y walks towards boy X = 5m

To find:

Distance boy Y would appear to be in the mirror to boy X

Solution:

According to the diagram, we can see that Boy X is 2m away from the mirror, and boy Y is 12m away from Boy X

So the distance of boy Y from the mirror would be,

12m + 2m = 14 m

Boy Y is 14 m away from the mirror.

Since boy Y has now walked 5 m ahead so the distance of Boy Y from the mirror is,

14m - 5m = 9m

Boy Y is 9m away from the mirror.

We need to find the appearance of the image of Boy Y to Boy X

Since Boy X is 2m added from the mirror we need to minus this distance from Boy Y who is 9m away

9m + 2m = 11m

Therefore, Boy Y appears 11m far in the mirror from Boy X.
