For storage 0.25 MB. How many seconds does it take to print text on a laser printer at a print speed of 61440 cpm

First, you need to convert the specified file size from megabytes to bits.

Since 1 MB contains 1024 KB, 1 KB contains 1024 bytes, and 1 byte contains 8 bits, we get:

0.25 * 1024 * 1024 * 8 = 2097152 bits.

We find the amount of information that a printer can print in 1 minute.

Since the size of one character is 8 bits, we get:

61440 * 8 = 491520 bits.

Determine the total print time of the printer in minutes.

To do this, divide the file size by 491520 bits.

We get:

2097152/491520 = 4.26 minutes.

We translate the specified time into seconds.

4.26 * 60 = 256 seconds.

Answer:

256 p.
