I have done this problem atleast 3 times now and after seeing examples I am just confused. When dealing with the transmission delay for example.. you would set it up as 20Mbit/ 20Mbps. Now. Wouldnt we need to change the 20Mbit to 160mbps? If so that would = 10.66.

If you can just show me how I need to be doing this problem it would be greatly appreciated.

We are sending a 20 Mbit test file from a source host to a destination host. All links in the path between source and destination have a transmission rate of 15 Mbps. Assume that the propagation speed is 2 108 meters/sec, and the distance between source and destination is 20,000 km. a) Initially suppose there is only one link between source and destination. Also suppose that the entire file is sent as one packet. The end-to-end delay(
