The data transfer rate over the adsl connection is 128000 bps. The file transfer over this connection took 120 seconds. How large is the file in Kbytes?

128,000 bits per second are transmitted per second. Let’s convert this value to kilobytes. Based on the fact that there are eight bits in one byte, and 1024 bytes in one kilobyte:

128000 bits = 128000/8 bytes = 128000/8/1024 kilobytes = 15.625 kilobytes per second.

We multiply this value by the time specified by the task – this will be the answer:

15.625 * 120 = 1875 kilobytes.
