# The data transfer rate over ADSL is 128000 bps connection. It took 16 seconds

The data transfer rate over ADSL is 128000 bps connection. It took 16 seconds to transfer the file through this connection. Determine the file size in KB.

Let’s determine what the volume of the file transferred using the ADSL connection, whose speed is 128000 bit / s, was, if from the condition of our problem we know for sure that this took 16 seconds:

128000 * 16 = 2048000.

Let’s determine how many kilobytes the volume will be equal to, which was calculated by us in the previous step:

1 byte is the same as 8 bits;

1 kilobyte is the same as 1024 bytes;

2048000: 8: 1024 = 250.

Answer: The size of the transferred file is 250 KB.
