To calculate the time it will take Carla to read the full assignment, we need to first determine how many sets of 4 pages she will read.
20 pages ÷ 4 pages = 5 sets of 4 pages
Each set of 4 pages takes Carla 10 minutes to read, so:
5 sets of 4 pages × 10 minutes = 50 minutes
Therefore, it will take Carla 50 minutes to read the full assignment.
To find out how long it will take Carla to read the full assignment, we need to determine how many sets of 4 pages are in 20 pages.
20 pages ÷ 4 pages per set = 5 sets
Since it takes Carla 10 minutes to read a set of 4 pages, we can multiply the number of sets by the time it takes to read a set.
5 sets x 10 minutes per set = 50 minutes
Therefore, it will take Carla 50 minutes to read the full assignment.
To find out how many minutes it will take Carla to read the full assignment, we need to calculate how many pages she can read in 1 minute and then multiply that by the total number of pages.
Given that Carla can read 4 pages in 10 minutes, we can calculate how many pages she can read in 1 minute by dividing 4 by 10:
4 pages / 10 minutes = 0.4 pages per minute
Now, since Carla has 20 pages to read, we can multiply the number of pages she can read in 1 minute (0.4) by the total number of pages (20):
0.4 pages per minute * 20 pages = 8 minutes per 20 pages
Therefore, it will take Carla 8 minutes to read the full assignment. So the correct answer is 9 minutes.
