Question 2 (3 points) A router (A) receives a 1400-byte datagram which is put into an output buffer for router B which at that time has 8,000 bytes waiting to be sent. The link to router B operates at 100 Mbps over fiber (v=200 m/us), and B is 2000 km away. How long (in sec) does it take before the datagram is fully received by B
