Final answer:

The person is approaching their image in the mirror at a speed of 4 m/s.

Step-by-step explanation:

When a person jogs towards a plane mirror, the distance between the person and their image in the mirror decreases at twice the rate of their speed. This means that if the person is jogging towards the mirror at a speed of 2 m/s, they are approaching their image at a speed of 4 m/s.
