Atwelve-hour clock is set at the correct time on the afternoon of may 17th. if the clock loses 6 minutes per day, what is the next calendar day on which it will show the correct time?

To figure this out, we want to keep adding a day until the clock loses a total of 12 hours

first to figure out how much time it takes to for the clock to lose an hour

so it takes 10 days to lose and hour
now to see how long it take to lose 12 hours

so 120 days from May 17th
