Homework Help: algebra

Posted by Anthony on Tuesday, December 11, 2007 at 11:36pm.

On Monday, Voltaire drove to town at 60 miles per hour. On Tuesday, he drove to town at 40 miles per hour. If the totaling traveling time for both trips was 15 hours, how far was it to town?

I know distance=(rate)(time).so I set it up like this...x=distance

X/(60)(15) + x/(40)(15)=

..but I end up getting the wrong answer...any advice on how to set up uniform motion problems dealing with ROUND TRIPS..thanks.
