Answer:
The distance of the epicenter from the seismic station is equals to 127 km(minimum). Using the data obtained from the seismic station, seismologists can read the lag time of 16.9 seconds of P waves before S waves detected. P (Primary) and S (Secondary) waves had an interval 16.9 seconds. P waves travel at 5 km/s while S waves do 3 km/s. That means P wave travels 60% faster than the S waves
The difference of P and S wave time is equals 16.9s:
