The data transfer rate over ADSL connections is 512 Kbps. The file transfer over this connection

The data transfer rate over ADSL connections is 512 Kbps. The file transfer over this connection took 4 minutes. Determine the file size in megabytes

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

4 minutes = 120 seconds

512 kilobits per second are transmitted per second. Let’s convert this value into megabytes. Assuming that there are eight bits in one byte, and 1024 kilobytes in one megabyte:

512 kilobits = 512/8 bytes = 512/8/1024 kilobytes = 0.0625 megabytes per second.

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

0.0625 * 120 = 7.5 megabytes.
