A 60KB file is transferred over some connection at 3072 bits per second. Determine the file size (in KB) that can be transferred in the same amount of time over another connection at 256 bits per second. Please provide one number in your reply – the file size in KB.

Let’s define the transmission time:
60 KB / 3072 bits per second = (60 * 1024 * 8 bits) / (3 * 1024 bits per second) = 20 * 8 seconds.
Let’s calculate the file size:
20 * 8 seconds * 256 bits per second = 5120 * 8 bits = 5 KB.
