Solve This Pzzlr: Rainy Dilemma

(Image credit: Flickr user Thomas ♫)

Neatorama presents our collaboration with Pzzlr, a site where you can always find a riddle to exercise your brain. Can you solve this one?

Four people need to get from point A to point B. Unfortunately it is pouring down rain and nobody wants to get wet. They have one umbrella between them which can keep two people dry at a time. Person 1 can make the trip from A to B in 1 minute, person 2 in 2 minutes, person 3 in 5 minutes, and person 4 in 8 minutes. Two people travelling together underneath the umbrella will go at the pace of the slower person. How can everyone get from A to B in no more than 15 minutes?
