Earthquakes produce several types of shock waves. The most well-known are the P-waves (P for primary or pressure) and the S-waves (S for secondary or shear). In the earth's crust, the P-waves travel at around 6.5 km/s while the S-waves move at about 3.5 km/s. The actual speeds vary depending on the type of material they are going through. The time delay between the arrival of these two waves at a seismic recording station tells geologists how far away the earthquake occurred.
If the time delay is 33 s, how far from the seismic station did the earthquake occur?
Ive already recieved no credit for this problem but am stuck on how to get started, I just would like a small hint as to how to get started thanks?
