Answer:To estimate the time it takes for a population to double, you can use the rule of 70. The rule of 70 states that you can approximate the doubling time (in years) by dividing 70 by the growth rate. In this case, the growth rate is 0.88%.
Doubling time ≈ 70 / Growth Rate
Doubling time ≈ 70 / 0.88
Doubling time ≈ 79.55 years
Therefore, with a population growth rate of about 0.88% per year, it would take approximately 79.55 years for the world's population to double. Keep in mind that this is a simplified calculation and assumes a constant growth rate, which may not be entirely accurate in the real world.
