Talking of relative velocity
Use vectors here
Here we see V1 and V2 are in opp direction
So if we are sitting in a train moving with velocity V1
V12=V1-(-V2)
The -ve sign of V2 indicates opposite direction
So basically the net result is addition of both speeds
V12=V1+V2
Here's a logical approach to understand
just assume case 1 Ur in a car A and a car B is moving in opposite direction
Now assume case 2 Ur in car A moving in some direction but car B is moving in same direction as car A
u will notice that u feel greater speed of car B since it's moving in opposite direction
