Jess recently started a business producing cosmetic products made from natural ingredients. She wants to advertise her products by distributing bags of samples in her neighborhood. She calculated that it takes a person 2 minutes to prepare one bag.
How many hours will it take to prepare 1200 bags of samples if Jess and 7 of her friends work simultaneously?

6 hours I believe. I got the answer by multiplying 1200 by 2 because 2 seconds per bag then you divide by 7 then take that answer and divide by 60 because 60 minutes in an hour. 
Since it takes 2 minutes per bag, multiply that by how many bags need to be prepared and you have 2400 minutes. Now divide that by 60 to find out how many hours it will take (and this is currently only for one person) and you'll get 40. Now since we have 8 people working together, divide 40 by 8, and there's your answer. It will take 5 hours.
