Question

what does the graph show?
the s and p waves travel the same distance through earths crust in the same amount of time.
the p wave travels through earths crust more quickly than the s wave travels.
it takes the p wave 18 minutes to travel 6,000 km through earths crust.
it takes the s wave 11 minutes to travel 8,000 km through earths crust.

Explanation:

By observing the graph, for the same distance, the travel - time of the P - wave is less than that of the S - wave. This indicates that the P - wave travels faster through Earth's crust. The other options can be disproven by looking at the graph: the S and P waves do not travel the same distance in the same time; the P - wave takes less than 18 minutes to travel 6,000 km; and the S - wave takes more than 11 minutes to travel 8,000 km.

Answer:

The P wave travels through Earth's crust more quickly than the S wave travels.
