Carla needs to complete her science homework. She has 20 pages to read and 14 questions. If it takes Carla 10 minutes to read 4 pages, how many minutes will it take her to read the full assignment. (1 point)
A. 50 minutes
B. 85 minutes
C. 9 minutes
D. 35 minutes
Carla needs to read 20 pages, and it takes her 10 minutes to read 4 pages, so it will take Carla 20 / 4 * 10 = <<20/4*10=50>>50 minutes to read the full assignment. Answer: A. 50 minutes.
To find out how long it will take Carla to read the full assignment, we need to calculate the total number of pages she needs to read and then divide it by the number of pages she can read in 10 minutes.
Carla needs to read 20 pages in total. To calculate how many 4-page sets are in 20, we can divide 20 by 4: 20/4 = 5.
This means Carla needs to read 5 sets of 4 pages to complete her assignment.
Since Carla can read 4 pages in 10 minutes, we can multiply the number of sets by 10 to find out how long it will take her to read the full assignment: 5 sets * 10 minutes = 50 minutes.
Therefore, the correct answer is A. 50 minutes.
To find out how many minutes it will take Carla to read the full assignment, we need to divide the total number of pages she needs to read (20) by the number of pages she can read in 10 minutes (4). This will give us the number of sets of 4 pages she can read in 10 minutes.
Total pages / Pages read in 10 minutes = Sets of 4 pages in 10 minutes.
20 / 4 = 5 sets of 4 pages in 10 minutes.
Since each set of 4 pages takes 10 minutes to read, we can multiply the number of sets (5) by the time it takes to read each set (10 minutes).
Sets of 4 pages x Time per set = Total time to read full assignment.
5 sets x 10 minutes = 50 minutes.
Therefore, Carla will take 50 minutes to read the full assignment.
The correct answer is A. 50 minutes.
