The data transfer rate through the dedicated channel is 131072 bps. It took 2 minutes to transfer the file over this connection. Determine the file size in kilobytes.

Let’s translate the time it took to transfer the specified file from minutes to seconds:

2 minutes = 60 * 2 = 120 seconds.

Let us find out how many bits determine the amount of information that was transmitted during this time, if it is known from the condition that the transmission rate was 131072 bit / s:

131072 * 120 = 15728640.

Let’s translate the result we got above from bits to kilobytes:

1 byte is the same as 8 bits;

1 kilobyte is the same as 1024 bytes:

15728640: 8: 1024 = 1920 KB.

Answer: 1920 KB.
