I recently went to a Kaplan
practice exam which was not so great as it was a paper test but it was free so can't complain but here is a question I came across which I had a problem with. Let me know if anyone an figure it out.
Steve gets on the elevator at the 11th floor of a building and rides up at a rate of 57 floors per minute. At the same time Joyce gets on an elevator on the 51st floor of the same building and rides down at a rate of 63 floors per minute. If they continue traveling at these rates, at which floor will their paths cross?
I'll post the answer a little later so everyone has a fair chance to answer.
