Today's Question - I'll catch you later - Al started riding his moped from home toward the picnic grove at noon. He travelled at a steady 4 mph. Bob started from the same spot at 2:30 and went at a steady rate of 5 mph. They both arrived at the same time. How long did Bob travel and how long was the trip?

Reveal Answer Answer - The class ran an hour longer than it would have if novice Sean had left things alone (9 + 5 hours = 2:00). Therefore, half of that hour it was going the wrong way and the other half hour correcting. Since the Abbot returned it at 11:30, then Sean must have pulled his prank at 11:00 - one half hour earlier.
