Homework Help: Algebra

Posted by JIM on Monday, September 24, 2007 at 10:50pm.

You commute 56 miles one way to work. The trip to work takes 10 minutes longer than the trip home. Your average speed on the trip home is 8 miles per hour faster. What is your average speed on the trip home?

I got to this point

xy=56
(x-8)(y+10)=56

I couldn't get any further than that. I'm not sure where to go with those equations.
