Long 2km, the base data rate o

[问答题]
Long 2km, the base data rate of 10Mbps with bus LAN, signal propagation speed 200m/μs, Calculate:
(1) 1000-bit frame received from the beginning to the end to send the maximum time?
(2) If the two sites furthest away from sending data at the same time, how long the two stations is found to conflict?

(1)1000bit/10Mbps+2000m/200(m/μs)=100μs+10μs=110μs
(2)2000m/200(m/μs)=10μs
