Question

a standard mp3 file at 128 bits per second (kbps) results in 0.96 mb file size per minute of audio play. however, there are other possible rates for audio files, even nonstandard ones. determine the rate in mb per minute for a file size 2.33 mb that plays for 4.5 minutes

Answer 1

To determine the rate in megabytes per minute for an audio file, divide the file size by the duration in minutes. For a 2.33 MB file that plays for 4.5 minutes, the rate is approximately 0.5178 MB per minute.

Step-by-step explanation:

The question is asking to calculate the rate at which an audio file of size 2.33 MB plays for 4.5 minutes. To find this rate, we need to divide the total file size by the number of minutes of audio play.

We use the formula:

Rate (MB/min) = File size (MB) ÷ Duration (minutes)

Substituting the given values:

Rate (MB/min) = 2.33 MB ÷ 4.5 minutes

Now, perform the division:

Rate (MB/min) = 0.5178 MB/min

The rate at which the audio file plays is approximately 0.5178 MB per minute.
