How long will it take a seismic wave to reach a receiving station 360 km away?

The time it takes for a seismic wave to reach a receiving station depends on the type of wave. For example, primary waves (P-waves) travel at speeds of about 5-8 km/s in the Earth's crust. If we assume an average speed of 6 km/s, it would take approximately 60 seconds for the wave to cover 360 km.
