Relative velocity is the velocity according to an observer. Eg. if a car is travelling 10ms-1 towards a bus travelling 10ms-1, the bus will appear to be travelling 20ms-1 relative to the car because the car sees the bus as approaching faster since the car is approaching the bus. So the car sees the bus travelling its own speed + the bus' speed. Hope that is a simple explaination. If you still dont understand jut look up youtube videos I find that helps. Science ready is usually good for physics

This is interchangeable right? So the bus also sees the car as moving at 20m/s?

Yes, the same logic applies
