S and P waves from an earthquake travel at different speeds and this difference helps in the determination of the earthquake "epicenter", (where the disturbance took place).

(a) Assuming typical speeds of 9.0km/s and 5.5 km/s for P and S waves, respectively, how far away did the earthquake occur if a particular seismic station detects the arrival of these two types of waves exactly 94s apart?

(b) Is one seismic station sufficient to determine the position of the focus? Explain.
