Homework Statement
Illustrate the concept that "the physical state of system A is correlated with the state of system B" by considering the momenta of cars on the M25 at rush-hour and the road over the Nullarbor Plain in the dead of night.
Relevant Equations
I know quantum correlation means that the particles are entangled and so the state of each cannot be determined independently of the other.
I know quantum correlation means that the particles are entangled and so the state of each cannot be determined independently of the other. However I'm not sure how it applies to this particular scenario - If there are more cars on the M25 I suppose we could say technically there are less on Nullarbor Plain, therefore they will move slower on the M25 due to traffic so have less momentum? Any help understanding how to link these to the concept would be greatly appreciated.

That's a terrible homework question. What I guess they might want to see: Discuss how the speed of a car is correlated with the speed of other cars. Consider the two given road scenarios as examples.
But cars are classical, we can describe their states independently.

This makes no sense to me at all! These systems have far too many classical characteristics to serve as a model for quantum systems. What's the QM analogy of "rush-hour"?
