The clock is showing $$11\text{am}$$ now.  When the hour hand has turned through $$165{}^{}\circ$$, what time will it be? 
Overseas Competition->Knowledge Point->Counting Modules->Permutations and Combinations->Combinations
Each hour, the hour hand turns $$30{}^{}\circ$$, so it will take $$5\frac{1}{2}$$ hours to turn $$165{}^{}\circ$$; the time will therefore be $$4.30\text{pm}$$.
