Can the s-p time method be used with one seismograph station to locate the epicenter of an earthquake?
The first step in this method is to collect several seismograms of the same earthquake from different locations. Then, the seismograms are placed on a time-distance graph. The seismogram tracing of the first P wave is lined up with the P-wave time-distance curve, and the tracing of the first S wave is lined up with the S-wave curve.The distance of each station from the earthquake can be found by reading the horizontal axis. After finding out the distances, a seismologist can locate an earthquake's epicenter.-New Boyz

The distance between an earthquake epicenter and the location of a seismograph can be calculated because?
4. shear waves and compression waves travel at different speeds, therefore the difference in arrival time can be used to fix the distance.
Geologists use the difference in the arrival times of P waves and S waves at a seismograph to determine?
The distance to the epicenter
What type of data do geologists use to locate an earthquake's epicenter?
Seismologists use the data from triangulated seismographs to locate an earthquake's epicenter. The difference in time between the arrival of p and s waves at a seismometer tells the distance to the epicenter of an earthquake. To get the exact location, scientists must collect data from at least three seismometers. The point where all three circles is the epicenter of the earthquake. +++ The Epicentre is generally obvious: it is the point of maximum disturbance on the surface. The centre of the actual slip is the Focus, and this has to be calculated from seismograph data by triangulating from wave velocities.
How is the fact that P waves travel more quickly the S waves used to determine the distance of an earthquake's epicenter from a seismograph station?
Given the difference in arrival times, you can determine the distance from the epicenter.

The distance to the epicenter
Is data about an earthquake from two seismographic stations enough information to locate the epicenter?
From Science Explorer Prentice Hall Earth Science: " Geologists use seismic waves to locate an earthquake's epicenter. Seismic waves travel at different speeds. P waves arrive at a seismograph first, with S waves following close behind. To tell how far the epicenter is from the seismograph, scientists measure the difference between the arrival time of the P waves and S waves. The farther away an earthquake is, the greater the time between arrival of the P waves and the S waves." Did this help?

How is the fact that P-waves travel faster that S-waves used to determine the distance of an earthquake epicenter from an seismograph station?
Using the difference in their arrival times and an estimate of their velocity of propagation you can calculate the distance of the earthquake epicentre from the seismometer recording station. If you do this from three or more different seismometer stations you can triangulate it's position. For more information please see the related question.
The distance between a seismic station and the earthquake epicenter is determined from the?
The difference in arrival times of P and S waves.
