Answer:
The answer is 600 minutes (10 hours)
Step-by-step explanation:
20 minutes = 1 student.
30 students x 20 = 600 minutes
600mins / 60 (because an hour has 60 mins) = 10 hours.
Answer:
it would take around 10 hours to grade all 30 papers
Step-by-step explanation:
if for one student it takes 20 minutes that means you would have to do 20 minutes 30 times which is 600 minutes. to convert that to hours you divide total minutes (600) by 60 which gives you 10 hours. no need for thanks
