To read 20 pages at a rate of 4 pages in 10 minutes, Carla will need 10/4 * 20 = <<10/4*20=50>>50 minutes.
To answer this question, we need to find out how many minutes it would take Carla to read 20 pages.
We're given that Carla can read 4 pages in 10 minutes. To find out how many pages she can read in 1 minute, we can divide the number of pages she can read in 10 minutes by 10.
4 pages / 10 minutes = 0.4 pages/minute
Now, we can find out how many minutes it would take Carla to read 20 pages. We can divide the number of pages by the number of pages she can read in 1 minute.
20 pages / 0.4 pages/minute = 50 minutes
Therefore, it would take Carla 50 minutes to read the full assignment. The correct answer is option C: 50 minutes.
To find out how long it will take Carla to read the full assignment, we can calculate the number of 4-page increments in the assignment and multiply that by 10 minutes.
Since Carla has a total of 20 pages to read, we can divide that by 4 (since Carla takes 10 minutes to read 4 pages) to find out how many 4-page increments there are.
20 pages / 4 pages per increment = 5 increments
Now that we know there are 5 4-page increments, we can multiply that by 10 minutes per increment to find the total time it will take Carla to read the full assignment.
5 increments * 10 minutes per increment = 50 minutes
Therefore, it will take Carla 50 minutes to read the full assignment.
