3. How far can an S-wave travel in 6 minutes 40 seconds?

1800km

Explanation:

This question will be answered using the attached S-wave graph.

The graph is plotted as time (y axis) against distance (x axis).

So, when

y = 6 minutes 40 seconds

x = 1.8 * 10³ km

So, we have:

x = 1.8 * 1000km

x = 1800km
