Carla needs to complete her science homework. She has 20 pages to read and 14 questions to answer. If it takes Carla 10 minutes to read 4 pages, how many minutes will it take her to read the full assignment?
Options:
35 minutes
50 minutes
85 minutes
9 minutes
Carla can read 4 pages in 10 minutes.
To read 20 pages, she will need 10/4 * 20 = <<10/4*20=50>>50 minutes.
Therefore, it will take Carla 50 minutes to read the full assignment.
The correct answer is 50 minutes.
To find out how many minutes it will take Carla to read the full assignment, we first need to determine how many sets of 4 pages are in 20 pages.
20 pages / 4 pages = 5 sets
Carla will need to read the 20 pages in 5 sets, so we can multiply the time it takes to read one set by 5.
10 minutes * 5 = 50 minutes
Therefore, it will take Carla 50 minutes to read the full assignment. The correct option is:
50 minutes.
To find out how long it will take Carla to read the full assignment, we first need to determine how many pages she can read in 1 minute.
We know that it takes Carla 10 minutes to read 4 pages, so we can calculate her reading rate as follows: 4 pages / 10 minutes = 0.4 pages per minute.
Now, we can calculate how long it will take Carla to read 20 pages by dividing the total number of pages by her reading rate: 20 pages / 0.4 pages per minute = 50 minutes.
Therefore, it will take Carla 50 minutes to read the full assignment.
So, the correct option is B) 50 minutes.
