Answer :
Final answer:
To read a 24 GB Blu-ray disc at a rate of 5 MB/s, takes approximately 81.92 minutes, with the closest answer being 80 minutes (Option B). Thus, the correct option is B) 80 minutes.
Explanation:
To calculate the time it takes to read the entire 24 GB capacity of a Blu-ray disk at a speed of 5 MB/s, we need to convert the capacity of the Blu-ray disk from gigabytes to megabytes and then divide by the read speed. There are 1024 megabytes in a gigabyte. So 24 GB is equivalent to 24 × 1024 MB = 24576 MB. Now, dividing the capacity in megabytes by the read speed gives us the time in seconds: 24576 MB ÷ 5 MB/s = 4915.2 seconds.
To convert seconds to minutes, we divide by 60: 4915.2 seconds ÷ 60 = 81.92 minutes.
The closest answer to 81.92 is 80 minutes, so the correct answer is B) 80 minutes.
