Two answer options:
1. According to the theory of relativity, the speed of light does not depend on the frame of reference. Based on this, the pulses move relative to each other at the speed of light
s = 300,000 km / s.
2.From the standpoint of classical mechanics, the speeds when moving towards each other are summed up
Cm = s + s = 2s.
