At midnight on Friday, Mia's clock showed the correct time as 0:00 am. At midnight on Saturday, her clock showed the time as 11:48 pm. At midnight on Sunday, her clock showed the time as 11:36 pm. At 6:00 am on Monday, Mia set her clock so that it showed 6:02 am. What is the time difference, in minutes, between Mia's clock and the correct time of midnight on Thursday the same week?
43 minutes
We know that a day is: 24 hours = 1440 minutes And we notice that Mary's clock skips 12 minutes every 24 hours. That means that Mary's clock is 12 / 1440 slower than a normal clock. From 6:00am on Monday to midnight of thursday, we have 1080 + 1440 + 1440 + 1440 = 5400 minutes So the difference is 5400 * 12 / 1440 = 45 minutes We substract the 2 minutes she added, and we get 43 minutes.
