Question 312201
<font face="Garamond" size="+2">


You can eliminate most of the complexity of this problem if you pretend to stand still and let your friend travel a 2 mph for *[tex \Large \frac{1}{3}] hour.


By the way, where would you ever find a 2 mile (or greater) long escalator?  You would think that the people who make up these questions would use their head for something besides a hat-rack.
