The first P-wave of an earthquake took 11 minutes to travel to a seismic station from the epicenter of the earthquake. What is the seismic station's distance to the epicenter of the earthquake and how long did it take for the first S-wave to travel that distance? Distance to epicenter: 3350 km/ S-wave travel time: 4 min 50 sec
Distance to epicenter: 3350 km/ S-wave travel time: 6 min 10 sec
Distance to epicenter: 7600 km/ S-wave travel time: 9 min
Distance to epicenter: 7600 km/ S-wave travel time: 20 min
