Looks like its just you and me Teague.


Is the answer 43?

43 (X-Y) = X2 -Y2

43 (X-Y) = (X-Y)(X+Y)

Since we know X and Y are not equal, X-Y cannot be zero. Therefore we can divide (X-Y) from each side leaving us with

43 = X+Y

As an effort to try to get a Teague sighting.............



Isaac and Albert wanted to take a vacation. They were debating how they could get to their hotel in the fastest manner. Isaac said, "We should go by train." But Albert said, "No, the train reaches the end of the line half way to the hotel -- we would have to walk the rest of the way. We should bike to the hotel instead." Isaac disagreed. So Albert biked the whole way to the hotel, while Isaac took the train for the first half of the journey and walked for the remainder.

The speed of the train turned out to be four times that of the bike's speed. The bike's speed turned out to be two times faster than walking speed. Who got to the hotel first?
