first, we do 30 dollars per 1 hour times 35 hours per 1 week.
30*35 = 1050 dollars per 1 week
now, we do 1050 dollars per 1 week times 50 weeks per 1 year.
1050*50 = 52500 dollars per 1 year
finally, we divide 52500 dollars per 1 year by 1,000,000 dollars earned overall and we get the fraction
400/21
that doesn't come out to an exact decimal, so we get either
400/21 years or the rounded decimal of
19.0476 years
so, approximately 19 years.
