The data transfer rate over a certain communication channel is 512000 bit / s

The data transfer rate over a certain communication channel is 512000 bit / s. it took 1.5 minutes to transfer the file over this connection. Determine the file size in kilobytes.

Speed is measured by the ratio of volume to seconds, so let’s convert the specified time into seconds:

1.5 minutes = 90 seconds

512,000 bits per second are transmitted per second. Let’s convert this value into kilobytes:

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

We multiply this value by the time specified by the task – this will be the answer:

62.5 * 90 = 5625 kilobytes.
