18 minutes because 6*2 is 12 and 3*6 is 18. it will take 6 minutes to do 4 problems, 9 minutes to do 6 problems , 12 minutes to do 8 problems, 15 minutes to do 10 problems, and 18 minutes to do 12 problems

3 min to complete 2 problems
___ min to complete 12 problems

It took her 6 min. Why. Divided 12 divided by 2 is 6. So if it took her 3 min to complete 2 problems then it took her 6 min to complete 12 problems.
