We are trying to figure out when we should start downloading apps in the app store to be the 25,000,000,000th download. The number is 24,658,507,655 downloads rights now at Friday 24th at 6:27 PM. The average number of downloads per minute is 34,237. I subtracted 25,000,000,000 the end number by 24,658,507,655 the downloads now getting the answer of 341,389,779 downloads left until the 25,000,000,000 app. So I divided 341,389,779 the number left and 34,237 downloads per minute to get 9,971. Than I divided 60 by 9,971 because there is 60 minutes in an hour. After that I got 166, I than divided 24 by 166 because that is how many hours in a day. I than got the answer of 7, making it 7 more days till it reaches the 25,000,000,000th download. If I started on Feb 24 at 6:30 PM knowing its a leap year and add seven days to that I am than at March 2 at 6:30 PM. I am guessing that the downloads will start to get faster towards the end so I am going to start downloading about 5:30 PM an hour before on March 2.
