How long would it take to download a 49 megabyte file as certain speeds
49 megabyte file could be:
A high quality song
A short video
A software update
A batch of photos
Etc
How long would it take at 47 kbps ($5 Month)
How long would it take at 1.5 Mbps ($20 Month)

How to calculate download times at given connection speeds
Figure out how many ____ are in the file you need to download
Figure out how many ____ per second your connection can download
Divide the total number of ____ that must be downloaded by the number of ___ that can be downloaded per second to get the number of seconds needed to download your file
Divide the seconds by 60 if you want to convert the time to minutes
9.
Example 1 = 49 megabyte file and 47 kilobit per second connection
Figure out how many bits are in the file you need to download
49 megabytes * 1024 *1024 * 8 = 411,041,792 bits
First 1024 converts megabyte to kilobytes
Second 1024 converts kilobytes to bytes
The 8 coverts bytes into bits
We will need to download 411,041,792 bits from the Internet to our computer.

Example 1 = 49 megabyte file and 47 kilobit per second connection
Figure out how many bits per second your connection can download
47 kbps * 1000 = 47,000 bits per second
The 1000 converts kilobits into bits
11.
Example 1 = 49 megabyte file and 47 kilobit per second connection
3 ) Divide the total number of bits that must be downloaded by the number of bits that can be downloaded per second to get the number of seconds needed to download your file
411,041,792 bits / 47,000 bits per second = 8745.6 seconds
12.
Example 1 = 49 megabyte file and 47 kilobit per second connection
4 ) Divide the seconds by 60 if you want to convert the time to minutes
8745.6 seconds / 60 = 145.8 minutes
(or about 2hrs and 26 minutes)
13.
Example 2 = 49 megabyte file and 1.5 megabits per second connection
Figure out how many bits are in the file you need to download
49 megabytes * 1024 *1024 * 8 = 411,041,792 bits
First 1024 converts megabyte to kilobytes
Second 1024 converts kilobytes to bytes
The 8 coverts bytes into bits
We will need to download 411,041,792 bits from the Internet to our computer.
14.
Example 2 = 49 megabyte file and 50 gigabit per second connection
2) Figure out how many bits per second your connection can download
1.5 Mbps * 1000 * 1000 = 1,500,000 bps
The first 1000 converts megabits to kilobits
The second 1000 converts kilobits into bits
15.
Example 2 = 49 megabyte file and 1.5 megabits per second connection
3 ) Divide the total number of bits that must be downloaded by the number of bits that can be downloaded per second to get the number of seconds needed to download your file
411,041,792 bits / 1,500,000 bits per second = 274 seconds
