The correct answer is - 47 years.
Explanation:
The doubling time of the population growth depends on the rate of population growth. The formula for the calculation of the doubling time is :
time (t) = log(N/N0)/r (time)
here,
N0 (initial population) = The population at time t = 0.
N (future population) = The population at time t.
r (rate) = The rate of population change as a function of t
by the formula
t = log (2/1)/0.015
t = 46.666 years or 47 years approx.
