A particular mp3 encoder can convert 93.0 kilobytes of music per second from a typical music CD. How many minutes will it take to convert 16.1 megabytes (Mb) of music from a CD

To answer this question, you need to convert the 16.1 megabyte into second first. If the rate is 93kb/second, then the calculation would be:

16.1 mb x (1000kb/mb) / (93kb/second) = 173.12 second.

Then 16.1 mb music will last for 173.12 second. After that you can convert it into minutes: 173.12 / (60second/min) = 2.885 minutes.
