Posted by Alaina on Monday, May 6, 2013 at 7:43pm.

Fabio stands atop his 16 foot ladder when he realizes that the ladder is slipping down the side of the building. He decides that the base of the ladder is moving away from the bottom of the building at a rate of 2 feet per second when it is 3 feet from the bottom of the building. How fast is Fabio falling at that instant?

my answer is 10.477 or 10.48 but it's wrong. please give guidance. thanks
