Unless Marion takes the train instead of driving, she can get to work on time only by leaving at least 45 minutes early.
If on time -> 45min early OR train
(inclusive OR, obviously)
the diagram that I like is this...
(not)[on time ==> leaves 45 min early] =======> Train
meaning that if she decided to forgo the "on time by leaving 45 min early" process, then she will have necessarily taken the train, assuming that she does show up to work on time.
CP: (not)T =======> [on time ==> leaves 45 min early]
meaning that if she does not use the train and does in fact show up to work on time, then she must have gone through the "on time by leaving 45 min early" process.
thoughts?
