Answer the following questions (make sure you show your work for the calculation): 1. Construct a X-T plot for both case 1 and 2, where X is offset (x-axis) and Tis two ways travel time (y-axis). Make sure to label the plots and print them 2. Which case (1 or 2) corresponds to horizontal interface and which one is dipping? Justify your answer. 3. For single horizontal layer: a) Estimate the layer velocity (V.s) and thickness using the TX curve method. b) Estimate the layer velocity (V) and thickness using the approximate TMX) formula, then compare the result with the velocity estimated in parta 4. For the single dipping layer case, calculate the layer dip angle, velocity, and thickness using T., To, and X.
