41. It takes Craig 20 minutes to type n pages. At these rates, how many hours will it take him to type 100 pages?
All i know is 20/n
you want to convert 100 pages to minutes.
Your conversion factor is
20 minutes = n pg
20min/n pg = 1
Now multiply vy that to cancel the unwanted units:
100 pg * 20min/n pg = 2000/n min
To find out how many hours it will take Craig to type 100 pages, we can use the information given in the problem.
We know that Craig takes 20 minutes to type n pages. So, we can set up a proportion to solve for the number of hours it would take to type 100 pages.
Since there are 60 minutes in 1 hour, we can convert the 20 minutes to hours by dividing it by 60:
20 minutes ÷ 60 minutes/hour = 1/3 hour
Now, we can set up the proportion:
20 minutes/ n pages = 1/3 hour / 100 pages
To solve this proportion, we can cross multiply and then solve for n:
20 minutes * 100 pages = n pages * 1/3 hour
2000 minutes * 1/3 hour = n pages
Simplifying further:
2000/3 minutes = n pages
Therefore, it will take Craig 2000/3 minutes to type 100 pages. To find his answer in hours, we can divide it by 60:
2000/3 minutes ÷ 60 minutes/hour = 2000/3 ÷ 60/1 = 2000/3 * 1/60 = 33.33 hours
So, it will take Craig approximately 33.33 hours to type 100 pages.
