Answer:
12 seconds.
Step-by-step explanation:
Let t represent time taken by code to sort an array of 24 elements.
We have been given that an algorithm takes 4 seconds to sort an array of 8 elements. We are asked to find the time it will take for same code to sort an array of 24 elements.
We will use proportions to solve our given problem.





Therefore, it will take 12 seconds for the same code to sort an array of 24 elements.
