If we say that an American has 5 days to his full-time job, and state to have 9 hours per working days, multiply it by probably 20 working days in a month. The product is 180 and multiplies it by 12 that refers to 12 months in a year and the product is 2,160. This product will be multiplied by 45 years of the course. So the amount of time that Americans will spend at their full-time jobs is 97, 200 hours.
