Brainteaser answer
At 2:12, the big hand is two-fifths of the way between the 2 and the 3. The little hand will be pointing the same direction, two-fifths of an hour after two.
One fifth of an hour is 12 minutes, so the big hand will be pointing in the right direction at 2:24, which is in 12 minutes!
