Riddle #1

You are walking in the forest with your friend Matt, your friend Joey, and your friend Beth. There is a wolf that you just found out about. You found out that it will take about 11 minutes for the wolf to catch up to you, and to get to safety you will have to climb an old rope ladder to get to some shelter away from the wolf. You can dash across in a minute, while Matt takes a minute and a half, Joey takes 5 minutes, and Beth takes 5 minutes and a half. Unfortunately the old rope ladder can hold only two people at a time. How can you all make it to safety?
