For this question, let the packet size L = 1000 bytes, the propagation speed s = 2.5 x 108 m/s, the link distance d = 2000 km, and the transmission rate R = 10 Mbps. Assume that 1 Mbyte (megabyte) = 1 x 106 bytes (SI definition). Answer these questions:

(a) If 5 packets arrive simultaneously and the queue is initially empty, what is the average queuing delay for all 5 packets.
