Question: An earthquake releases two types of traveling seismic waves, called transverse and longitudinal waves. The average speeds of the transverse and longitudinal waves in rock are 8.8 km/s and 5.9 km/s respectively. A seismograph records the arrival of the transverse waves 69 s before that of the longitudinal waves.
Part A: Assuming the waves travel in straight lines, how far away is the center of the earthquake?
