How to model transmission line when surge impedance and travel time parameters are given for study of transient analysis?

Suppose there is a transmission line of 20m. I have following data surge impedance is 350 ohms and travel time is 300 m/µsec. By using the formulae: Z0 = 60 ln b/a; -> (1) C = 2*pi*ᵋ/...
