The modem transmits data at a speed of 56 Kbps. The transfer of the text file took 4.5 minutes. Determine how many pages the transmitted text contained if it is known that it was represented in Unicode encoding (1 character-1 byte), and on one page – 3072 characters.

Let’s convert the time it took to transfer the file into seconds:

4.5 * 60 = 270.

Let us find out how many Kbps the amount of transmitted information will be determined if it is known from the condition that the transmission rate is 56 Kbps:

56 * 270 = 15120.

Let’s translate the amount of information we received from Kbits to Kbytes:

1 KB is the same as 8 KB;

15120: 8 = 1890.

Let’s define the maximum amount of information on 1 page in Kbytes:

3072 * 1: 1024 = 3.

Let’s find out the number of pages:

1890: 3 = 630.

Answer: 630.
