1. The average rate of growth for a certain language is equal to the difference of native speakers now and then, divided by the number of years.

2. Let's calculate the average rate of growth for languages A and B:

- Language A: \(\frac{# \ of \ native \ speakers \ now - # \ of \ native \ speakers \ then}{# \ of \ years} = \frac{450 \ million - 330 \ million}{5} =\) 24 million per year.
- Language B: \(\frac{# \ of \ native \ speakers \ now - # \ of \ native \ speakers \ then}{# \ of \ years} = \frac{300 \ million - 260 \ million}{5} =\) 8 million per year.

3. The difference between the two will be 24 million - 8 million = 16 million per year.

4. Our answer is: 24,000,000 and 16,000,000.
