Actually, if you started right at 120, then they would only cross 10 times. Since they start on top of each other AND finish that way too, they don't count as crosses, and only 10 occur.

But the teaser doesn't require the time period to start with the hands on top of each other. Every other circumstance provides 11 crossings, which is therefore the more correct answer.

I'll echo paul726. I wonder how the teaser read before it was corrected.

Good teaser. It may have been edited. The answer seems OK to me now.
