Information from a refraction seismic survey for a three-layer case in which V3, V2, and V1 is involved is given in Exercise Table 18.2. Draw the time-distance curve similar to that in Example Problem 18.3 and in Figure 18.22. Find V1, V2, and V3 based on the slope of the lines in the plot. Calculate Z1 and Z2 using both the critical distance method and the time intercept method. Explain any discrepancies in your answers
