Lily, I calculated the number of days in a month as 365/12 in order to get a good “average” number.

Ryan, good question – but actually, no. Leap years don’t occur on century-ending years that aren’t evenly divisible by 400. So 1700 was not a leap year. Neither was 1800 or 1900. The year 2000 WAS a leap year (2000 is evenly divisible by 400), but 2100 won’t be.

So an “average” century has 24.25 leap days… that’s why we added that extra text in. I knew someone would mention it if I didn’t!

What’s an average century? Won’t there always be 25 leap years?

Oh, right, the thing that goes into the other thing is smaller relative to the other things.. Of course!

I think guesstimating is too much to ask, considing how close they are.
I figured it out by counting 1200 months in a century versus 1440 minutes in a day.
At this point, I can’t tell you why this works (in part because my mind has moved on), but it is a pretty good approximation.

My deep knowledge of the Rent soundtrack allowed me to answer this one. 525 600 minutes in a year, so I roughly divided that by 12-ish. And of course, days in a century is easy.

IP, doing so would have made the total of minutes in a month a bit higher or lower, but it would not have affected the correct answer one bit.

You know, some months are 28 days long while some are 31. The question should have been a 30 day month or at least specified how long the month was.

i got this one, too.
365×100=36,500 days in a century
60×25=1500
1500×30=approximately 45,000 minutes in a month

I got this one too! Yay! Just out of curiosity, how many days per month are you using?
