Answer:

29 years

Step-by-step explanation:

The Chinese population stands at 1.3 billion, growing at an annual rate of 0.49%. To determine how many years it will take to reach 1.5 billion, we utilize the following calculation:

After x years, the projected population will be

1.3 * 1.0049^x

This leads us to solve:

1.3 * 1.0049^x = 1.5

1.0049^x = 1.5/1.3

x log 1.0049 = log(1.5/1.3)

x = log(1.5/1.3)/log(1.0049)

x = 0.062 / 0.002122

x = 29.25 years

<pThus, at a rate of 0.49%, it would take approximately 29 years for the Chinese population of 1.3 billion to grow to 1.5 billion.
