The image moves with a speed of 5m/s w.r.t the mirror . In other words the image comes closer to the person w.r.t 10m/s. Priyansh Sangule · 2 years, 3 months ago

I remember when we made an experiment on mirrors and we learned that the distance from the image to the mirror and the distance from the real object to the mirror is the same. Hence, the image "moves" at \(5\) m/s also. Marc Vince Casimiro · 2 years, 4 months ago
