Suppose  trains or  items our bodies are shifting in contrary guidelines at u m/s and v m/s, then their relative velocity is = (u + v) m/s.

If  trains of period a meter and b meters are shifting in contrary guidelines at u m/s and v m/s, then, the time taken via way of means of the trains to move every other = (a+b)/(u + v) sec.
