Question

Файл размером 210 Кбайт передается через соединение со скоростью 5880 бит в секунду. Определите, на сколько Кбайт меньше можно передать за это время со скоростью 840 бит в секунду.решение пожалуйста я не понимаю

Answer 1

210 Кбайт = 1720320 бит
1720320/5880= 292.571429 секунд - время
292.571429*840= 245760 бит можно передать со скоростью 840 бит/с
1720320-245760=на 1474560 бит (собственно ответ)

Answer 2

Calculation of File Transfer Time

To determine how many kilobytes (KB) less can be transferred at a speed of 840 bits per second (bps) compared to a speed of 5880 bps, we need to calculate the time it takes to transfer the file at each speed.

Given: - File size: 210 kilobytes (KB) - Speed of the first connection: 5880 bits per second (bps) - Speed of the second connection: 840 bits per second (bps)

To calculate the time it takes to transfer the file at each speed, we can use the formula:

Time (in seconds) = File size (in bits) / Speed (in bps)

Let's calculate the time it takes to transfer the file at each speed:

1. Speed of 5880 bps: - File size in bits = 210 KB * 8 bits per byte = 1680 kilobits (Kb) - Time = 1680 Kb / 5880 bps = 0.2857 seconds

2. Speed of 840 bps: - File size in bits = 210 KB * 8 bits per byte = 1680 kilobits (Kb) - Time = 1680 Kb / 840 bps = 2 seconds

Now, let's calculate the difference in the amount of data that can be transferred in the given time at each speed:

1. Speed of 5880 bps: - Time = 0.2857 seconds - Amount of data transferred = Speed * Time = 5880 bps * 0.2857 seconds = 1680 bits

2. Speed of 840 bps: - Time = 2 seconds - Amount of data transferred = Speed * Time = 840 bps * 2 seconds = 1680 bits

Since the amount of data transferred is the same at both speeds (1680 bits), we cannot transfer any additional data at a speed of 840 bps compared to a speed of 5880 bps.

Therefore, the answer is that you cannot transfer any kilobytes less at a speed of 840 bps compared to a speed of 5880 bps.
