i need help on the part b i don't understand how people are getting 52, but i know you have to divide 1636 and 52 but how do you get 52

1 Answer

  • A. The number of hours per person would be the number of hours divided by the number of people. 
    B.  A week is 1/52 of a year. So that would be 1/52 of the answer from a.
    342 billion / 209 million = 1,636.36364 = 1,636 hours per year 
    1,636 / 52 = 31.461 per week
