The wall clock strikes every full hour, as many strikes as there are hours. The pauses between punches last as long as the punches themselves. At 6:00, exactly 22 seconds passed from the beginning of the first stroke to the end of the last stroke. How long will the clock strike at 12:00?

Correct answer:

t12 =  46 s

Step-by-step explanation:

t6=22 s t6 = 6 u+5 u = 11u  u=t6/11=22/11=2 s  t12=12 u+11 u=12 2+11 2=46 s
