Nilsa is working on a 60-minute test. there are 20 questions on the test. if it takes her 20 minutes to complete 12 0f the questions, what is the greatest amount of time on average she can spend on each of the remaining 8 questions?

She used 20 minutes of the 60 minutes total. So she has 60 - 20 =40 minutes left.
She answered 12 question of the 20 questions total. So she has 20 -12=8 questions left.
The average will be (the time left) / (the questions left)
= 
= 5 minutes/question

The correct answer is .44
