Answer:
   7.92 years
Step-by-step explanation:
We want to find t such that ...
   3 = 2^(t/5)
where 2^(t/5) is the annual multiplier when doubling time is 5 years.
Taking logs, we have ...
   log(3) = (t/5)log(2)
   t = 5·log(3)/log(2) ≈ 7.92 . . . years
It will take about 7.92 years for the population to triple.
