.341423082\33800=10101\60\168\24=7 days

 

I took the twenty five billion and subtracted the 24,658,576,918 from it and got 341423082 then  I divided 341423082 33,800 and that equals 10101 and divide that by 60 and that equals 168 then you dived 168 by 24 because there are 24 hours in a day and it equals 6 hours and 23 hour so basically 7 days
