Jon's MENSA Question of the Day

--posted by JRJ on 9/27/2005

We have a slow set of trains here. One train runs from A to B at 19 miles per hour. The other runs from B to A at 21 miles per hour (it's a slightly improved model). One hour before the trains pass each other, how far apart are they?

40 miles apart. one hour prior, the first train was 19 miles "west" of their meeting place, and the second train was 21 miles "east" of it. 19 + 21 = 40 miles apart.
