A person is 1.9 m tall. Where should he place the top of a mirror on the wall so he can see the top of his head? Assume his eyes are 4.8 cm below the top of his head. Find a minimal vertical distance from the level of the person’s eyes to the top of the mirror.

Answer 1

0.024 meters

`(4.8)/(2) =2.4` cm

And in meters it is : 0.024 meters

The minimal vertical distance from the level of the person’s eyes to the top of the mirror is 0.024 meters.
