2. Earthquakes produce seismic waves, which travel through Earth. Primary waves, or P-waves, are longitudinal. They can travel through both solids and liquids. Secondary waves, or Swaves, are transverse. They can travel through solids only. P-waves travel at approximately El] kmfs, and Swaves travel at approximately 4.5 kmls. Following an earthquake, vibrations are recorded at seismological stations around the world. a} Calculate how long P-waves and S-waves take to travel from an earthquake to a seismological station that is 2.4)\" [13 km away.
