Hello.
The question is: The land area in the world is about 1.5x10^6 km^2. Using present world population growth rates determine how many years will elapse before one person will have only 1m^2 of land ("standing room only").
growth rate = 1.68 world population (1995)= 5,759 million.
the answer in the back of the book is 610 years from 1995.
Ok so this is what i'm doing: I use the equation N/No=e^(lambda)(t). I convert 1.5x10^6 km^2 to 1.5x10^11 m^2 so I use current world population for No=5.759x10^9 and N= 1.5x10^11 and lambda = .0168 then solve for t(time). My answer is nothing like 610 yrs. Any help would be greatly appreciated. thanks!
