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 at the server at the right. the speed of light propagation delay on each link is 3x108 m/sec. note that the transmission rates are in mbps and the link distances are in km. assume a packet length of 12000 bits. give your answer in milliseconds
