How long does it take to a p wave to travel 1600 km?

The speed of P-waves (primary waves) in the Earth's crust is typically around 5 to 8 kilometers per second. Assuming an average speed of 6 km/s, it would take approximately 267 seconds, or about 4.5 minutes, for a P-wave to travel 1600 km. The actual time can vary depending on the specific geological conditions.
