The data transfer rate is 512000 bps. A 125 KB file was transferred. Determine the transmission time per second.

First, let’s translate the file transfer rate in bits into kilobytes. Based on the fact that there are eight bits in one byte, and 1024 kilobytes in one byte:

512000 bits = 512000/8 bytes = 512000/8/1024 kilobytes = 62.5 kilobytes per second.

The information stream is capable of transmitting 62.5 kilobytes per second per second. Let’s divide the size of the information to be transferred by the bandwidth. This will be the solution to the problem:

125 / 62.5 = 2 seconds.
