3/4 as many people: 4/3 as many hours
2.25 hours
How to be yours? Haha
To find out how long it will take 6 janitors to clean the college grounds, we can use the concept of "man-hours" or "work-hours."
Let's first calculate the total man-hours required to clean the college grounds. We know that 8 janitors can clean the college grounds in 3 hours. So, the total man-hours required is 8 janitors * 3 hours = 24 man-hours.
Now, we can find out how long it will take 6 janitors to complete the same amount of work. Since the total man-hours required is still 24, we can divide that by the number of janitors to find the time it will take.
So, 24 man-hours รท 6 janitors = 4 hours.
Therefore, it will take 6 janitors 4 hours to clean the college grounds.
