There is a cage at Chester Zoo that contains both peacocks and wild pigs. If there is a total of 30 eyes and 44 feet, how many of each are in the cage?

Mr. Greenwich has a clock that chimes on both the hours and the half hours. The clock strikes once for each half hour, once for one o'clock, twice for two o'clock, three times for three o'clock, etc. As Mr. Greenwich walked into his house one day, he heard the clock chime once. A half hour later it chimed once again. A half hour later it chimed once, and a half hour later it chimed once again. Since the clock is working properly, what time was it when Mr. Greenwich entered his house?
