Question

скорость передачи данных через adsl-соединение равна 128000 бит с. Сколько времени в минутах займет передача файла объемом 5 мбайт по этому каналу пожалуйста, помогите ;)

Answer 1

128 000 бит = 16 000 байт

 

5 мбайт = 5120 К байт = 5 242 880 байт

 

Скорость передачи = 5 242 880/16 000=327.68 сек = 5.46(3) мин

Answer 2

Speed of ADSL Connection

The speed of data transmission through an ADSL (Asymmetric Digital Subscriber Line) connection is given as 128,000 bits per second (128,000 bps).

Time to Transfer a 5 MB File

To calculate the time it will take to transfer a file with a size of 5 megabytes (5 MB) through this ADSL connection, we need to convert the file size from megabytes to bits.

1 megabyte (MB) is equal to 8 megabits (Mb). Therefore, a 5 MB file is equal to 40 megabits (Mb).

Using the speed of the ADSL connection, which is 128,000 bits per second (128,000 bps), we can calculate the time it will take to transfer the file.

Time (in seconds) = File size (in bits) / Speed of the connection (in bits per second)

Time (in seconds) = 40,000,000 bits / 128,000 bps

Calculating this, we find that the time it will take to transfer the 5 MB file through the ADSL connection is approximately 312.5 seconds.

To convert this time to minutes, we divide the time in seconds by 60:

Time (in minutes) = Time (in seconds) / 60

Time (in minutes) = 312.5 seconds / 60

Therefore, it will take approximately 5.21 minutes to transfer a 5 MB file through this ADSL connection.

I hope this helps! Let me know if you have any further questions.
