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.
