In my math class we did a project on the 25 billionth app winner. On February 24th at 6:27 p.m. there were 24,658,507,655 downloads during the contest. If you subtract that from 25,000,000,00 you get 341,492,345 downloads left. You then divide that by the avg. number of downloads per minute, which is around 33,800 to get 10,103 minutes until we reach 25,000,000,00.  If you divide that by 60 you get the number of hours left which is 168 hours.Then you divide that by 24 to get the number of days which is 7 days left until we reach 25 billion. That would mean we would reach the 25 billionth app winner on March 2nd at 6:27 p.m.  you would want to start downloading apps at around march 2nd 6:20.
