Answer to Question 1

Answer: I'd expect some variation on this diagram from the text:

Answer to Question 2

Answer: First I would measure the amount of time that elapsed between the arrival of the first P wave and the arrival of the first S wave on seismogram 1. Then I would use the chart showing P and S wave travel times versus distance to determine the distance from seismogram 1 to the epicenter. Then I would repeat that with seismograms 2 and 3. Finally, I would triangulate the distances, using three circles of different radii, and the point where all three circles intersect would be the epicenter.
