The sound will approach the mountain at the same speed, v, irrespective of the speed of the rocket. This is because sound will always travel at the same speed as long as properties of air remain the same.

Therefore, sound will approach the mountain at velocity v in both 100 m/s and 200 m/s of the rocket.
