+1926 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! :)

+1926 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!
