Transmission Delay is 10.416ns/m~12.5ns/m per circle trip
For 1m of cabling the signal has to travel 2m: Hence propagation speed
Speed=110.416∗10−9/2=192.013∗106m/sSpeed = \frac 1 {10.416*10^{-9} / 2}= 192.013*10^{6}m/s
192.013∗106C0=64.04%\frac {192.013*10^6} {C_0} = 64.04\%
Speed=112.5∗10−9/2=160∗106m/sSpeed = \frac 1 {12.5*10^{-9} / 2}= 160*10^{6}m/s
160∗106C0=53.3%\frac {160*10^6} {C_0} = 53.3\%
