there is a bridge. it's narrow and treacherous, especially at night when it's raining. sure enough, 4 folks come along the path one rainy night. they have a single flashlight, which is necessary so that they can be sure they will have good footing on the bridge. at most, 2 folks can cross at a time.
the 4 folks are a diverse group. there is a fat old monk, who can cross the bridge in 11 minutes. the middle-aged mom can cross in 5 minutes. the champion mountain climber can cross in 2 minutes. lastly, the professional sprinter can cross in 1 minute.
time is of the essence. all 4 folks have to cross the bridge safely in 19 minutes or less. the pairs that cross the bridge must travel together at the slowest person's pace. therefore if the sprinter and the monk cross together, it takes 11 minutes. if the monk then returns the flashlight to the others, 11 more minutes will have passed, and the group will have failed.
again, please post answers on the corresponding "answers" thread. I'll post any clarifications on this thread.
