The 1982 Ethernet specification allowed between any two stations up to 1500 m of coaxial cable, 1000 m of other point-to-point link cable, and two repeaters. Each station or repeater connects to the coaxial cable via up to 50mof drop cable. Typical delays associated with each device are given in Table 2.6 (where c = speed of light in a vacuum = 3108 m/s). What is the worst-case round-trip propagation delay, measured in bits, due to the sources listed? Show your work.
