Hmm, I may or may not disagree with you on what the output should be. I
can't speak for his assignment, but in real life, I would think it would be
more useful to perform the simulation some number of times, printing out th=
e
number of  seconds it took to get to 500 passengers each time, and the
average of all the trials. It's not clear to me from the description of the
assignment whether the requirement is for the results of a single trial
(rather silly) or an average.

Anyway, I did this, for fun, and consistently got an average of around 833
seconds on average for 100000 trials. Anyone else give this a shot? I'm
curious to see whether different implementations give different results. Th=
e
standard deviation seems to be pretty high.
