Carla needs to complete her science homework. She has 20 pages to read and 14 questions to answer. If it takes Carla 1 minutes to read 4 pages, how many minutes will it take her to read the full assignment? (1 point)
A50 minutes
B9 minutes
C85 minutes
D35 minutes
If it takes Carla 1 minute to read 4 pages, then it will take her 5 minutes to read 20 pages (20 pages / 4 pages per minute = 5 minutes).
Therefore, it will take her 5 minutes to read the full assignment. Answer: B9 minutes.
To find the number of minutes it will take Carla to read the full assignment, we need to first calculate how many groups of 4 pages there are in 20 pages.
20 pages / 4 pages per group = 5 groups
Since it takes Carla 1 minute to read 4 pages, she will need 1 minute per group.
Therefore, she will need 1 minute per group x 5 groups = 5 minutes to read the full assignment.
Therefore, the correct answer is option B: 9 minutes.
To solve this problem, we first need to determine how many minutes it will take Carla to read one page. We are told that she can read 4 pages in 1 minute, so we can calculate Carla's reading speed as follows:
1 minute / 4 pages = 0.25 minutes/page.
Now we can find out how many minutes it will take Carla to read the full 20-page assignment:
20 pages * 0.25 minutes/page = 5 minutes.
Therefore, it will take Carla 5 minutes to read the full assignment. However, none of the given answer choices match this result.
