Answer:
the unit rate is equal to 140 kilobytes/sec
Explanation:
A kilobyte per second is the unit of measurement used in computing to measure the speed of transfer of information in a network. To calculate the rate is only to divide the kilobits over time. In general, it can be said that if the network bandwidth is large, the data transmission speed will be larger. The calculation can be done as follows:
2520 kilobytes/18 seconds = 140 kilobytes/sec
