Nilsa can spend at least 5 Minutes on each remaining question. Take 60 minutes - 20 minutes to get 40 minutes then divide by 8 questions to get 5 minutes / question

since Nilsa already used 20 mins on the test there are 40 mins left so
there are 40 mins and 8 questions left. 40/8 equals 5 so 5 mins is the
greatest amount of time on average she can spend on each of the 8 remaining questions
