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?

EPICENTER DISTANCE (x 10' km)
Distance -time graph is a graph wherein the gradient of the
al to the speed of the object. The greater the gradient (steeper li
ter the object is moving. If an object moves a along a straight line,
ce travelled can be represented by a distance time graph.
