## How long would it take to count to a trillion?

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.
