Problem Analysis

We are given the transmission speed of an ADSL connection (256,000 bits per second) and the time it took to transfer a file (51 seconds). We need to determine the size of the file in kilobytes (KB).

Solution

To find the size of the file in kilobytes, we need to convert the transmission speed from bits per second to kilobytes per second and then multiply it by the time taken in seconds.

1. Convert the transmission speed from bits per second to kilobytes per second: - 1 byte = 8 bits - 1 kilobyte (KB) = 1024 bytes - 1 kilobyte (KB) = 1024 * 8 bits

Therefore, the transmission speed in kilobytes per second is: - 256,000 bits per second = (256,000 / 8) kilobytes per second

2. Multiply the transmission speed in kilobytes per second by the time taken in seconds: - File size in kilobytes = (256,000 / 8) * 51

Let's calculate the file size in kilobytes using the above formula.

Calculation

File size in kilobytes = (256,000 / 8) * 51

Answer

The size of the file is approximately 8,064 kilobytes.
