Study the graph about seismic waves.

graph of p & s wave travel times, showing travel time in minutes across distance in kilometers for p and s waves. s wave starts at zero kilometers, zero minutes, and increases to 10,000 kilometers, 25 minutes. p wave starts at zero kilometers, zero minutes and increases to 10,000 kilometers, 13 minutes.

what does the graph show?

the s and p waves travel the same distance through earth’s crust in the same amount of time.
the p wave travels through earth’s crust more quickly than the s wave travels.
it takes the p wave 18 minutes to travel 6,000 km through earth’s crust.
it takes the s wave 11 minutes to travel 8,000 km through earth’s crust.
