We are sending a 30 mbit mp3 file from a source host to a destination host. all links in the path between source and destination have a transmission rate of 10 mbps. assume that the propagation speed is 2 * 108 meters/sec, and the distance between source and destination is 10,000 km. the end to end delay(transmission delay plus propagation delay) is:
a. 3.05 seconds.
b. 3 seconds.
c. 6.1 seconds.
