Question

Интернет-тариф "Ночь" с 7:00 до 24:00 обеспчивает максимальную скорость передачи данных по каналу 2,4 мбит/секунду и с 24:00 - 7:00 - 4 Мбит в секунду. Определите, сколько секунд потребуется на загрузку файла объёмом 5 Мбайт при максимальной скорости, если закачка началась за 10 секунд до полуночи?

Answer 1

В байте 8 бит. 8 мегабайт это 8*8 мегабит. 8*8/4=( для меня слишком много )

Answer 2

Calculating File Download Time

To calculate the time required to download a file of 5 MB at the maximum speed provided by the internet tariff "Night," we can use the following formula:

Time (in seconds) = File Size (in Megabytes) / Speed (in Megabits per second)

Given: - File size = 5 MB - Maximum speed from 7:00 to 24:00 = 2.4 Mbit/s - Maximum speed from 24:00 to 7:00 = 4 Mbit/s - Download started 10 seconds before midnight

First, let's convert the file size to megabits: 5 MB = 5 * 8 = 40 Megabits

Now, we can calculate the time required to download the file at each speed and add the times together to get the total time.

At the speed of 2.4 Mbit/s: Time = 40 Megabits / 2.4 Mbit/s = 16.67 seconds

At the speed of 4 Mbit/s: Time = 40 Megabits / 4 Mbit/s = 10 seconds

Adding the times together: Total time = 16.67 seconds + 10 seconds = 26.67 seconds

Therefore, it will take approximately 26.67 seconds to download the 5 MB file at the maximum speeds provided by the "Night" internet tariff, given that the download started 10 seconds before midnight.
