A 1024 byte file is transferred over a connection in 64 milliseconds. Determine the time, in milliseconds, that a 4K file can be transferred over the same connection.

Size of the transferred file = transfer time · transfer rate. Note that the file size in the second case is 4 times the file size in the first case. Since the file transfer rate is the same, the time it takes to transfer a 4K file over the same connection is also 4 times longer. It will be equal to 64 * 4 = 256 milliseconds.
