Counting To A Trillion - Math Central

Subject: Trillions? Name: Art Keck Who is asking: Other Level: All

Question: If I counted one dollar every second, would it take 31,000 years to count to a trillion? If not, could you please explain how long it yould take?

Thanks Art

Hi Art,

There are 60 seconds in a minite so you would count $60 in one minute. There are 60 minutes in an hour so you would count 60x60 = $3600 in one hour. There are 24 hours in a day so you would count 24X60x60 = $8,6400 in one day. There are 365 days in a year so you would count 24X60x60x365 = $31,536,000 in one year.

To find how long it would take to count to a trillion dollars divide 1 trillion by 31,536,000. That is 1,000,000,000,000/31,536,000 = 31,709.79 years.

Cheers, Penny
