Learning Task 4: Study the activity. Follow the procedures indicated in the activity before answering the questions. Study the graph. Make use of the four questions to learn more about the concepts of distance graph. 1. An epicenter station is 4,000 km away. How long after the first P-wave did the first S-wave arrive? 2. An epicenter station is 5,600 km away. How long after the first P-wave did the first S-wave arrive? 3. How far can an S-wave travel in 6 minutes 40 seconds? 4. How far can a P-wave travel in 6 minutes 40 seconds?

The greater the gradient ( steeper line), the faster the object is moving. If an object moves a along a straight line, the dis- tance travelled can be represented by a distance time graph.
