I used rand() for both departure time and traveling time, assuming all the
times were equally likely. You bring up an interesting point about going
from B -> A. In my simulation, I only considered vehicles going in one
direction. Seems like the specification is unclear about whether they are
leaving every 5-35 seconds from both cities or just one. Though if they're
going from both directions, there's certainly no guarantee that you will
ever move a total of 500 from one to the other.
