Notice

On August 21 I am planning to perform a major update to the site. I can't give a specific time in which the update will happen other than probably sometime between 6:30 a.m. and 8:00 a.m. (Central Time, USA). There is a very small chance that a prior commitment will interfere with this and if so the update will be rescheduled for a later date.

I have spent the better part of the last year or so rebuilding the site from the ground up and the result should (hopefully) lead to quicker load times for the pages and for a better experience on mobile platforms. For the most part the update should be seamless for you with a couple of potential exceptions. I have tried to set things up so that there should be next to no down time on the site. However, if you are the site right as the update happens there is a small possibility that you will get a "server not found" type of error for a few seconds before the new site starts being served. In addition, the first couple of pages will take some time to load as the site comes online. Page load time should decrease significantly once things get up and running however.

1. The width of a rectangle is 1 m less than twice the length.  If the area of the rectangle is 100 m2 what are the dimensions of the rectangle? [Solution]

2. Two cars start out at the same spot.  One car starts to drive north at 40 mph and 3 hours later the second car starts driving to the east at 60 mph.  How long after the first car starts driving does it take for the two cars to be 500 miles apart? [Solution]

3. Two people can paint a house in 14 hours.  Working individually one of the people takes 2 hours more than it takes the other person to paint the house.  How long would it take each person working individually to paint the house? [Solution]
