Quesiton: Earthquakes produce seismic waves that travel through the earth.The speed of longitudinal seismic waves, called P waves, is 8000m/s. Transverse seismic waves, called S waves, travel at a slower4500 m/s. A seismograph records the two waves from a distantearthquake. If the S wave arrives 3.5min after the P wave, how far away was the earthquake? You canassume that the waves travel in straight lines, although actualseismic waves follow more complex routes. In kilometers.
