Question

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

Answer 1

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

Answer 2

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
