Hmmm, what is "the law of unlimited growth"? In any case, this looks like exponential growth to me.

The most basic formula for exponential growth is

A = P*e

Here 800 = 500*e

ln(1.6units) = r*1hr or ln(1.6units)/1hr = r or

A = 500*(1.6)

Substitute 5 for t to answer the first question, i.e.

A = 500*(1.6)

To answer the second part set A=20,000

20,000=500*(1.6)

40 = (1.6)

It looks to be slightly less than 8 hrs. You can verify this.
