Test Your Knowledge Tuesday

The answer to last week's tester: Three. In the worst case, the first two socks you take out will consist of one black sock and one white sock. The next sock you take out is guaranteed to match one or the other.

This week challenge:
A mountain goat attempts to scale a cliff sixty feet high. Every minute, the goat bounds upward three feet but slips back two. How long does it take for the goat to reach the top?

Feel free to post answers in the comments section, or return next Tuesday to find out what the answer is.

Your time...starts...NOW!
