Question

V = 128000 БИТ/ С I = 625 КБ -------- НАЙТИ T - ? С

Answer 1

Ответ:

128000/8=16000байт/с

625*1024=640000байт

Т=640000/16000=40с

Answer 2

To find the time (T) in seconds given the volume (V) in bits and the data rate (I) in kilobytes per second, we can use the following formula:

$T = \frac{V}{I} \times \frac{8}{1000}$

Given values: $V = 128,000$ bits $I = 625$ kilobytes per second

First, we need to convert kilobytes to bits: $I = 625 \text{ KB/s} = 625 \times 8 \times 1024 \text{ bits/s}$ (1 byte = 8 bits, 1 kilobyte = 1024 bytes)

Now, plug the values into the formula:

$T = \frac{128,000}{625 \times 8 \times 1024} \times \frac{8}{1000}$

Solving this equation will give us the time (T) in seconds. Let's calculate:

$T \approx \frac{128,000}{625 \times 8 \times 1024} \times \frac{8}{1000}$ $T \approx \frac{0.15625}{625 \times 1024} \times 8$ $T \approx \frac{0.15625}{640,000} \times 8$ $T \approx 0.00000000024375 \times 8$ $T \approx 0.00000000195 \text{ seconds}$

So, $T \approx 0.00000000195$ seconds, or approximately $1.95 \times 10^{-9}$ seconds.
