Answer 2

So there's 6 billion people as of July 18th, 1999

4.2 births and 1.7 deaths occur each seconds

That's a net gain of 2.5 births every second

So how many births is that in a minute? In an hour? And then in a day?

And then multiply by 365 to find out how many more people are added to the population in 1 year

And so how many years would it take to gain an additional 1,000,000,000 population?

You would just divide that number
1,000,000,000 / (net gain of births per year)

Answer 3

ok so if there is
31,536,000 secs in a year than there is
31,536,000*2.5 ppl born every year is that correct?

Answer 4

60* 60 * 24 * 365 gets you 31,536,000 seconds in a year so that's correct

and so yeah
2.5 * 60* 60 * 24 * 365

would tell you how many are born in a year

Answer 5

u get 78,840,000

Answer 6

mhmm

and so how many years for you to reach a billion people if each year you have like 78.8 million people added to the population

Answer 7

oh ok
its around 12

Answer 8

yeah 12.68

and so we were in July 1999

12 years after that

and then it's 0.68 of a year which is more than half a year so it would probably extend into the next year

Answer 9

ok so arounf 2012?

Answer 10

yeah, that's what I would say
