A man sitting on a chair looks into a plane mirror that is 2.5 m away fromhim. He sees the image of a chart that faces the mirror and is 0.5 m behindhim. How far away from him does the image of chart appear to be?(A) 6.5 m(B) 5.5 m(C) 7.5 m(D) 3.5 m​

Answer»

ANSWER:

(A) 6.5 m

Explanation:

The plane mirror is 2.5m away from him and the chart is 0.5 m far BEHIND him so the distance from the chart to the plane mirror is

2.5 m + 0.5 m = 3 m

And the distance from the chart to the man in the plane mirror is 3 m + 3 m + 0.5 m = 6.5 m.

We TOOK 3 m + 3 m bcoz we are also CALCULATING the distance of the chart in the mirror, so we doubled up the distance.

Thank you :)
