Where did I go wrong, I answered 151,200 which was wrong. Here is the question If your puppy is 3.5 months of age, how many minutes is this? Calculate for a month with 30 days (don't forget about significant figures). Sorry I published this as a poll originally, it was a mistake.

Think step by step. Show what you did. And is this a chemistry? I think it's a simple math problem.

This was on my chemistry quiz. Here is what I did:
24 hour x 60 minutes = 1440.00
1440 x 105 = 151,200. 3.5 months at 30 days per month = 105 days.
I thought this was pretty simple, but the correct answer is 150,000 minutes and I do not see how.
Actual lenght of a day from my researh is 23.56 hours, but that does not come out to the 150,000.
or did I miss the fact that it said significant numbers and I should of rounded down to 150,000.

Yeah, it's a simple case of sig figs. I don't like that this was on a chemistry quiz though, even if the point was to test dimensional analysis and significant figures. I prefer that they be tested in a chemistry problem...

Thank you for the input, just a case of making something more complicated then what it really was.

That's sidereal day, used only in astronomy.
