Full solution

Q. In 20172017, the estimated world population was 7.57.5 billion. Use a doubling time of 3535 years to predict the population in20622062
  1. Calculate Years Difference: question_prompt: What will the world population be in 20622062 if it was 7.57.5 billion in 20172017 and it doubles every 3535 years?
  2. Determine Doubling Periods: Calculate the number of years from 20172017 to 20622062. 20622017=452062 - 2017 = 45 years.
  3. Use Whole Number: Determine how many doubling periods there are in 4545 years. 4545 years // 3535 years per period == 1.28571.2857 periods.
  4. Double Population Once: Since populations can't double a fraction of a time, we'll use the whole number of doubling periods, which is 11.
  5. Double Population Once: Since populations can't double a fraction of a time, we'll use the whole number of doubling periods, which is 11. Double the population once because we have one full doubling period. 7.57.5 billion ×2=15\times 2 = 15 billion.
