Riddle.... cross the river?!


Question:

Riddle.... cross the river?

okay. lets start. (excuse my english, i'm afrikaans)
there is 4 guys who has to cross a river in 14 minutes...
They each take a different amount of time to paddle to the other side. the times the take is: One man needs 1 minute to cross, another man needs 2 minutes, another guy 5 minutes and the last one 7 minutes.
There is one boat, this boat can only take 2 persons at a time. the person who will take the longest to paddle to cross the river, has to paddle. for instance, if the 1 min guy and the 7 min guy paddles across, it takes 7 minutes. get them all to the other side within 14 minutes! how will u do it

When u answer, and your speaking of the guy who takes 1 min, just say number 1. etc.
