I need help with this question  1. Plot the travel-time data on the graph in Fig. A11.2.1. 2. Label the curve that represents travel times of P-wave first arrivals. Now do the same for the two lines/curves associated with S- and surface-wave first-arrivals, respectively. 3. Briefly explain why these points (and all similar points from other earthquakes) occur along three discrete lines or curves.
