This Travel Time ? Distance is the result of a single ?shot? at x=0m. It only shows the first arrivals.a) find the velocities of all layers involved and describe the structure in the subsurface that results in such a refraction response.b) determine the velocities of all layers involved and describe the interfaces (e.g. depth, dip, planar vs. non- planar).c) draw a sketch of the subsurface model.d) Derive the interpretation equation from ray - path considerations and document your calculation
