The data transfer rate over the ADSL connection is 256000 bps. It took 39 seconds for the file to transfer over

The data transfer rate over the ADSL connection is 256000 bps. It took 39 seconds for the file to transfer over this connection. Determine the file size in KB.

File size (Q) = bit rate (v) * file transfer time (t)
The formula itself looks like this: Q = v * t
First, let’s find the size of the file in bits. To do this, substitute the known data: Q = 256000 * 39 = 9984000 (bit)
Next, let’s convert the file size from bits to Kbytes. For this you need:
1) The size of the file in bits is converted into bytes. To do this, divide 9984000 by 8 = 1248000 (bytes)
2) Convert the file size in bytes to Kbytes. To do this, divide 1248000 by 1024 = 1218.75 = 1219 (KB)
Or you can write these actions in abbreviated form: 9984000: (8 * 1024) = 1218.75 = 1219 (KB)
Answer: 1219 (KB)
