## Ted Ed Bridge Riddle

There are four people who need to get to the other side of the bridge, each with their own time needed to get across said bridge. Even worse, the bridge can only support two of them for each trip (and the person with the longer time is counted when traveling in the pair). Oh and it's like dark and there is only one flashlight so a person who has crossed the bridge has to come back for a return trip in order to lead another person across once again. See, riddles are 'fun'.

Person A can get across in 1 minute, Person B does it in 2 minutes, Person C crosses in 5 and slowpoke sloth human needs 10 minutes. You need to get everybody to the other side in under 17 minutes. How do you do it?
Hint: Technically, it is NOT less than 17 minutes but exactly 17 minutes. "You need to get everybody to the other side in under 17 minutes."
A&B across (2mins)... A comes back (1min)... C&D across (10mins)... B comes back (2mins)... A&B across (2mins)
