Problem 1: (15 Points) COMPUTING END-END DELAY (TRANSMISSION AND PROPAGATION DELAY) Consider the figure below, with three links, each with the specified transmission rate and link length. Transmission rate: 1 Mbps Link Length: 500km Find the end-to-end delay (including the transmission delays and propagation delays on each of the three links, but ignoring queueing delays and processing delays) from when the left host begins transmitting the first bit of a packet to the time when the last bit of that packet is received Note that the transmission rates are in Mbps and the link distances are in Km. Assume a packet length of 4000 bits. Give your answer in milliseconds, round your answer to two decimals after leading zeros
