To determine how long it will take Carla to read the full assignment, you need to find out how many sets of 4 pages are in 20 pages and then multiply that by the time it takes to read each set.
If it takes Carter 10 minutes to read 4 pages, we can calculate the time to read all 20 pages as follows:
-
Find the number of sets of 4 pages in 20 pages: \[ \frac{20 \text{ pages}}{4 \text{ pages/set}} = 5 \text{ sets} \]
-
Multiply the number of sets by the time taken for each set: \[ 5 \text{ sets} \times 10 \text{ minutes/set} = 50 \text{ minutes} \]
So, it will take Carla 50 minutes to read the full assignment.
The answer is D) 50 minutes.
