A 4000 KB file is transferred over a certain connection within 1 minute. Determine the file size (in KB) that can be transferred over this connection in 45 seconds.
First, let’s determine the speed of file transfer over this connection.
v = I1 / t1 = 4000 KB / 1 min = (4000 * 1024 * 8) bits / 60 s = (400 * 1024 * 4) / 3 bits / s.
The file size that can be transferred over this connection in 45 seconds is I2 = v * t2 = (400 * 1024 * 4) / 3 bit / s * 45 s = 24576000 bits = 24576000 / (1024 * 8) kB = 3000 kB.
Answer: The size of a file that can be transferred over this connection in 45 seconds is 3000 KB.
