7.
When the World Wide Web first became popular in the 1990s, download speeds reached a maximum of about kilobits per second. Approximately how many minutes would the download of a -megabyte song have taken at that speed? (Note that there are kilobits in a megabyte.)
Answer: B
Small hint:
Convert megabytes to kilobits first
Big hint:
kilobits divided by kilobits per second gives seconds
Solution:
The song has kilobits. At kilobits per second, the download takes seconds, which is minutes.
Thus, the correct answer is B.
