The data transfer rate over the ADSL connection is 128000 bps. How long will it take to transfer a 500KB file over this channel?

To solve this problem, you need to know that: 1 byte = 8 bits, 1 kilobyte = 1024 bytes.
1. Let’s translate the data transfer rate from bit / s to kb / s:
128000 bits = 128000/8 = 16000 bytes
16000 bytes = 16000/1024 = 15.625 kilobytes.
Connection speed: 15.625 kilobytes per second.
2. Determine the time of transmission of a 500 kilobyte file via this channel:
500 / 15.625 = 32 sec.
Answer: 32 seconds.
