If you walk towards a plane mirror at a speed of 1.2 m/s, how fast will you approah your image i the mirror

When you walk towards the plane mirror with a speed of 1.2 m/s, the image also moves at the same speed with respect to the mirror. This means that the image is also moving at a speed of 1.2 m/s in the direction opposite to your motion. As you are walking towards the mirror, so the mirror will seem to be moving towards you with the speed 1.2 m/s. As the mirror seems to be approaching you and the image is also moving in the direction opposite to you,
so the resultant speed of the image = 1.2 + 1.2 = 2.4 m/s
​Therefore, you will approach your image with a speed of 2.4 m/s.
