Question

On average, how much faster is it to download media files using fast broadband compared to regular broadband?

What is the average download time per MB for fast broadband?

For regular broadband?

For a video I viewed the file size is 25.1MB If the file size is represented in gigabytes (GB), multiply that number by 1,000 to convert to megabytes (MB).

Using the average download times you computed, what should be the download time using fast broadband? What would it be for regular broadband?

How does your download time compare to these estimates? Do you have fast broadband, regular broadband, or something else?

Explanation / Answer

On average, it is approximately 4.85 times faster to download media files using fast broadband compared to regular broadband. This was calculated by taking an average of speed advantage of all the media files.

Average download time per MB for fast download = avg(3.5/3 + 21/18 + 120/110 + 318/265 + 750/600 + 1260/1250 + 3900/4000) = 1.122 sec/MB

For regular broadband:

= avg(19/3 + 108/18 + 600/110 + 1390/265 + 3120/600 + 6300/1250 + 18900/4000)

=5.428 sec/MB

For file size of 25.1 MB,

for fast broadband, time = 25.1*1.122 = 28.16 seconds

For slow broadband, time = 25.1*5.428 = 136.24 seconds
