How long would it take you to count to one billion, reciting the numbers one after another?

Answer 1

Those numbers would get pretty long at the end... "nine hundred and ninety nine thousand four hundred and fifty nine" I would guess an average of 5 seconds per number.

(5 sec/number) x 1,000,000,000 numbers x (1 min/60 sec) x (1 hr/60 min) x (1 day/ 24 hr) = 57870.3703704 days

57870.3703704 days x 1 yr/365 day = 158.548959919 years
