The average data transfer rate over a certain communication channel is 28,800 bit / s. How many seconds will it take to transmit a 640 * 480-pixel color image over this channel, provided that the color of each pixel is encoded with 3 bytes?

Let’s determine what total number of pixels the image will contain, which, according to the problem statement, has dimensions of 640 by 480:

640 * 480 = 307200.

Let us determine what the size of the transferred file will be in bytes, if it is precisely known from the condition of our problem that 3 bytes are required to encode the color of one pixel:

3 * 307200 = 921600.

Let’s translate the volume we received above from bytes to bits:

921600 * 8 = 7372800.

Let’s determine how many seconds it will take to transfer:

7372800: 28800 = 256.

Answer: 256 p.
