Suppose an earthquake's P waves travel at an average speed of 6 kilometers per second, and its S waves travel at an average speed of 3.4 kilometers per second. How long will it take the P waves to reach a recording station that is 100 kilometers from the focus? How long after the P waves will the S waves reach the same station? Give me the answer and tell me how you got your answer. *
Remember the formula rate x time = distance!
