An earthquake releases two types of traveling seismic waves, called transverse and longitudinal waves. the average speed of the transverse and longitudinal waves in rock are 9.1 km/s and 5.7 km/s respectively. a seismograph records the arrival of the transverse waves 71 s before that of the longitudinal waves. assuming the waves travel in straight lines, how far away is the center of the earthquake?
