One day while I was at school, the electricity went out at home. When I left for school that morning, all the clocks were working and agreed that the time was 6:30. When I got home they all said different times. The wind-up clock, which was unaffected by the electricity, read 5:21. The analog electric clock stops running when you unplug it from the wall, and it starts up where it left off when you plug it back in. That clock said it was 3:50. My digital electric clock, which resets itself to midnight when the electricity goes out, flashes until you correct the time. It was flashing 6:03am. Assuming the electricity went out just once, what time did it go out, and how long was it off.

It was off for 1 hour 31 minutes:
5:21 minus 3:50 = 1:31
It went came back on 6 hours and 3 minutes before you got home (at 5:21). Thus the power was lost at:
5:21pm minus 1:31 minus 6:03 = 9:47 am
or, using military time:
17:21 - 1:31 - 6:03 = 09:47

i like this emotional and telling poem. Tears pass so abundantly that finally the middle can replace into indifferent. yet this capability will come back,the gentle will return to heat your soul only as a results of fact the comforting lights return after a electric powered capability outage. This poem is so properly written and provocative. I do like it. thank you.
