The data transfer rate over the ADSL connection is 128,000 bps. How long will it take to transfer a 625K

The data transfer rate over the ADSL connection is 128,000 bps. How long will it take to transfer a 625K file over this connection?

To solve this problem, you first need to convert the specified information volume of the file from kilobytes to bits.

Since 1 KB contains 1024 bytes, and 1 byte contains 8 bits, we get:

625 * 1024 * 8 = 5122500 bits.

Find the time of transferring the file through this connection.

To do this, we divide the file size by the transfer rate.

We get:

5122500/128000 = 40.01 seconds.

We accept the file transfer time equal to 40 seconds.

Answer: It takes 40 seconds.
