The following puzzle appeared about a year ago; however, I just saw it today. Is there a solution to this puzzle? If so, please explain.

4 men need to cross a river. They only have 1 boat which holds a max of 2 people. The slowest man always rows the boat.

It takes man 'A' - 10 mins to row across the river
man 'B' - 5 mins to row across the river
man 'C' - 2 mins to row across the river
man 'D' - 1 min to row across the river

How can they all get across the river in no more than 17 minutes?
