Time Lines



1. The time is 2:12.
2. The time is 9:48.

The hour hand is exactly on a line every 12 minutes, so we only need to look at times ending in 00, 12, 24, 36, and 48.
The hands exactly overlap at 12:00. They are 5 lines apart at 11:00 and 1:00, and farther apart at other hours.
At times ending in 12, the hands are closest at 2:12, where they are 1 line apart.
At times ending in 24, the hands are closest at 4:24, where they are 2 lines apart.
At times ending in 36, the hands are closest at 7:36, where they are 2 lines apart.
At times ending in 48, the hands are closest at 9:48, where they are 1 line apart.

Chris's Birthday

  If today is January 1st, and December 31st was Chris' birthday and she turned 8, and on December 30 Chris was 7, and this year Chris will turn 9, then next year Chris is turning 10.

X-Men

  Cyclops. Why? Because the other names don't have any repeated letters

The Most Intelligent Prince

  White. The king would not select two white hats and one black hat. This would mean two princes would see one black hat and one white hat. You would be at a disadvantage if you were the only prince wearing a black hat. If you were wearing the black hat, it would not take long for one of the other princes to deduce he was wearing a white hat. If an intelligent prince saw a white hat and a black hat, he would eventually realize that the king would never select two black hats and one white hat. Any prince seeing two black hats would instantly know he was wearing a white hat. Therefore if a prince can see one black hat, he can work out he is wearing white. Therefore the only fair test is for all three princes to be wearing white hats. After waiting some time just to be sure, you can safely assert you are wearing a white hat.
