To find the greatest amount of time on average that Nilsa can spend on each of the remaining 8 questions, we need to know the total time available for the remaining questions.
Nilsa has a total of 60 minutes on the test and it took her 20 minutes to complete 12 of the questions. Therefore, she spent 20/60 = 1/3 of the time on those 12 questions.
To find the remaining time, we subtract the time spent on those 12 questions from the total time: 60 minutes - 20 minutes = 40 minutes.
Now we can calculate the average time per question for the remaining 8 questions by dividing the remaining time by the number of remaining questions: 40 minutes/8 questions = 5 minutes per question.
Therefore, the greatest amount of time on average that Nilsa can spend on each of the remaining 8 questions is 5 minutes.
