There was a contest that Mr.Oldfield challenged us to and the challenge was to figure out when to start downloading  to win the contest. And at 6:27 pm feb. 24 there were 24,658,507,655 And if you subtract that from 25,000,000,000 than u get 341,389,779 than after that i divided 341,389,779 by 34,200 and I got 9,982 and then I divided that number by 60 and got 166 hours And then I divided by 24 and got 6 days until the 25,000,000,000 billionth download and if you add that to feb 24 than u get march the 2 because it was on a leap year so I would start downloading and march 2 at 5:45 to win the contest.
