»In which we have a story problem

A pretty girl leaves Union Square at 1730. At the same time, a man with a hat begins walking west-south-west on a one-point-three-mile route home'ards, a route that exactly matches several MUNI routes. At the height of rush hour, who will reach their destination first?

Answer: Our man is faster than a speeding MUNI bus. And he had time to stop at the shop and pick up some fiery orange-red lilies.

I am still a little perplexed as to how surface transit moves at an effective 3 mph during rush-hour. No, wait, it's coming to me: bus routes run on secondary roads, and so are subject to stops at each intersection. Some times the buses need to stop for traffic control on one side of the intersection, and then a bus stop on the other side of the intersection -- two stops in three bus-lengths.
