A 3 KB file is transferred after some connection for 600 seconds.

A 3 KB file is transferred after some connection for 600 seconds. How many seconds will a 256 byte file be transferred over the same connection?

Option number 1.

Determine how many times the size of the first file exceeds the size of the second file:

1 kilobyte is 1024 bytes:

3 * 1024: 256 = 12.

Let’s determine how many seconds the time will be expressed, which will be required to transfer the second file:

600: 12 = 50.

Answer: 50.

Option number 2.

Let us determine what the information transfer rate will equal, if we measure it in bytes / s:

3 * 1024: 600 = 5.12.

Let’s determine how long it takes to transfer the second file:

256: 5.12 = 50.

Answer: 50.
