Challenge problems annoy me, figuratively and literally, especially when there's a twist in the story as well. 


So, I discovered this problem a couple of days ago, and ummm, help?


On one side of a riverbank, there are two 200 lb. adults and two 100 lb. children. They have a rowboat, which anyone can row, but the boat can only hold a maximum of 200 lbs. How will they manage to get everyone across the river using only the rowboat? They can't swim! Can you come up with a solution?


How is this even possible? 


Thanks! :)

Oh wait! That's so smart. 


I totally forgot that the children could row the boat back!


I was confused since only one adult could fit on the boat, meaning it would be "impossible" to succeed! I totally missed out on that LOL. 


Well, thanks a lot CPhill!
