Question:

The speed of longitudinal waves, called P waves, is 7274.0 m/s. Transverse waves, called S waves, travel at a slower 3803.0 m/s. A seismograph records the two waves from a distant earthquake. If the S wave arrives 4.47 min after the P wave, how far away was the earthquake?

Speed of Wave:

A wave carries energy along with it, there are no particles to travel along with the wave. The speed of wave indicates how fast the phase of the wave is traveling with time, which in turn indicates how fast the energy is carried by the wave.
