Plot the travel-time data on the graph in Fig. A11.2.1. E. Imagine that an earthquake occurred this morning. The first P-waves of the earthquake were registered at a recording station in Houston at 11:06:12.6 UTC (expressed as hours:minutes:seconds), and the first S-waves arrived at the same Houston station at 11:06:17.1 UTC. Use the travel-time graph (Fig. A11.2.1) to answer each of the following questions.

Plot the travel-time data on the graph in Fig. A11.2.1.

E. Imagine that an earthquake occurred this morning. The first P-waves of the earthquake were registered at a recording station in Houston at 11:06:12.6 UTC (expressed as hours:minutes:seconds), and the first S-waves arrived at the same Houston station at 11:06:17.1 UTC. Use the travel-time graph (Fig. A11.2.1) to answer each of the following questions.

1. What is the S-minus-P time interval of the earthquake? Express your answer in decimal minutes.            min

2.Use the curves you drew on Fig. A11.2.1 to estimate the distance from the earthquake’s epicenter to the Houston seismograph station.            km
