To estimate how many years it will take Marissa to complete 20 puzzles, we need to find the average number of puzzles she completes per year.

Given that Marissa completes 4 to 6 puzzles a year, we can take the average by adding the lower and upper limits and dividing by 2.

(4 + 6) / 2 = 10 / 2 = 5 puzzles per year

Now, we can use this average to estimate the number of years it will take to complete 20 puzzles. We divide the total number of puzzles (20) by the average number of puzzles completed per year (5).

20 / 5 = 4 years

Therefore, it would take Marissa approximately 4 years to complete 20 puzzles, given her average rate of completing 4 to 6 puzzles a year.
