30 hours because if there are 6 people working, each person will do 150 bags. it takes 300 minutes for each person to do 150 bags (150*2). it will take 1800 minutes for 6 people to do 900 bags (300*6). divide 1800 by 60 (minutes) and you get 30 hours
Answer:
It take 5 hours to prepare 900 bags of samples if Ashley and 5 of her friends do the work.
Step-by-step explanation:
1 person prepare 1 bag in 2 minutes
We are supposed to find How many hours will it take to prepare 900 bags of samples if Ashley and 5 of her friends do the work?
No. of persons = 6
Since 1 person 2 minutes to prepare 1 bag.
So, 6 persons prepare 6 bags in 2 minutes
6 persons prepare 1 bags in minutes =[tex]\frac{2}{6}[/tex]
6 persons prepare 900 bags in minutes =[tex]\frac{2}{6} \times 900[/tex]
= 300 minutes
Now, 60 minute = 1 hour
So, 300 minutes = [tex]\frac{1}{60} \times 300[/tex]
= 5 hours
Hence it take 5 hours to prepare 900 bags of samples if Ashley and 5 of her friends do the work.
