Today's Question - A monk named Sandy - In teaching his class in Medieval thinking, Brother Eric begins class at 9:00 a.m. by setting a 5 hour hourglass on the window sill. Later when no one is looking, impish novice Sean turns the hourglass over. At 11:30 Abbot Art notices the hourglass looks off and returns it to its original posture. Finally, at 3:00 p.m. the sand runs out and amid student grumbles, the class ends. What time did novice Sean turn the glass?

Reveal Answer Corner 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.
