March Maths Puzzle (for a chance to win a €25 Carn Voucher)

Four friends want to cross a bridge. Only 2 people can cross at one time. It is a dark and stormy night and there is only one torch between them to guide them. The water is rising fast so every minute counts. Sean takes one minute to cross, Amanda takes two minutes to cross, Helen takes four minutes to cross and Jane takes eight minutes to cross.

What is the FASTEST time in which they can all get across?
