Question

When the World Wide Web first became popular in the 1990s, download speeds reached a maximum of about 56 kilobits per second. Approximately how many minutes would the download of a 4.2-megabyte song have taken at that speed? (Note that there are 8000 kilobits in a megabyte.)

Accepted Answer

Notice that the number of kilobits in this song is 4.2 8000 = 8 7 6 100. We must divide this by 56 in order to find out how many seconds this song would take to download: 87610056 = 600. Finally, we divide this number by 60 because this is the number of seconds to get the answer 60060=10.
