Q. In 2017, the estimated world population was 7.5 billion. Use a doubling time of 35 years to predict the population in2062
Calculate Years Difference: question_prompt: What will the world population be in 2062 if it was 7.5 billion in 2017 and it doubles every 35 years?
Determine Doubling Periods: Calculate the number of years from 2017 to 2062. 2062−2017=45 years.
Use Whole Number: Determine how many doubling periods there are in 45 years. 45 years /35 years per period =1.2857 periods.
Double Population Once: Since populations can't double a fraction of a time, we'll use the whole number of doubling periods, which is 1.
Double Population Once: Since populations can't double a fraction of a time, we'll use the whole number of doubling periods, which is 1. Double the population once because we have one full doubling period. 7.5 billion ×2=15 billion.
