Question 632744: Problem: One day I was at school,the electricity went out at home. when I left for swim practice that morning,all the clocks were working and the time was 6:30am.When I returned home they all said different times. the wind -up clock,which was unaffected by the loss of electricity,have a time of 5:21pm. my math clock, which stops when the electricity is off and runs when the electricity is on, gave a time of 3:50 pm. My digital clock, which resets to midnight when the power goes off and continues to run from that point,have a flashing time of 6:03 am. Assuming the electricity went out only once, what time did it go out and for how long?
