A 20KB file is transferred over some connection at 1024 bits per second. Determine how many seconds faster you can transfer

A 20KB file is transferred over some connection at 1024 bits per second. Determine how many seconds faster you can transfer the same file over another connection at a speed of 2048 bits per second.

Let’s determine the transmission time through the first connection:
20 KB / 1024 bits per second = (20 * 1024 * 8 bits) / (1024 bits per second) = 160 seconds.
The speed of information transfer through the second connection is twice as fast as through the first. Therefore, the transfer time over the second connection will be 80 seconds.
Thus, through the second connection, you can transfer the file for 80 seconds
