Earthquakes generate shock waves that travel through the Earth's interior to other parts of the world. The fastest of these waves are longitudinal waves and are called primary waves, or p-waves. A p-wave has a very low frequency, typically around 0.050 Hz. If the speed of a

p-wave with this frequency is 8000 m/s, what is its wavelength in kilometers?
