Can you solve the below puzzle….. :)

My friend asked this question… he got this question from one aptitude book.
In a film shooting, a man is running towards a vertical mirror with a speed of 10 m/s along a line which is perpendicular to the plane of the mirror. The mirror is also moving towards the man with a speed of 6 m/s along the same line. Find the speed of the man’s image in the mirror with respect to the man. (The image of the man forms on the other side of the mirror such that the distance between the image of the man and the mirror is equal to the distance between the man and the mirror.)

(1) 16 m/s
(2) 22 m/s
(3) 26 m/s
(4) 8 m/s
