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.

There can actually be a 25-hour time difference between certain locations in the world. The International Date Line passes between the islands of Samoa and American Samoa. It is not a straight line, but "zig-zags" around various island chains. Therefore, Samoa and nearby islands have one date, while American Samoa and nearby islands are one day behind. Daylight saving time is used in some islands, but not in others—further shifting the hours out of sync with natural time.
