Question

What time did an earthquake occur if the first P-wave was recorded at 9:40am, after traveling 2000km?

Answer 1

According to the information presented in the graph, the earthquake occurred at 9:37 am.

The graph shows the relationship between the time (minutes) and the distance (km) that the P waves of an earthquake took to travel.

This graph shows two lines, a red one representing the S wave and a blue one representing the P wave.

According to this graph, the earthquake waves took about 3 minutes to travel the 2000km where they were first detected.

So the answer is 9:37 am, because at 9:40 am I had already traveled 2000 km.
