A seismographic station receives S and P waves from an earthquake, separated in time by 16.2 s. Assume the waves have traveled over the same path at speeds of 4.50 km/s and 8.20 km/s. Find the distance from the seismograph to the focus of the quake.

Expert Answer

Step 1

Given information:

Speed of S wave (Vs) = 4.5 Km/s

Speed of P wave (Vp) = 8.2 Km/s

Let “ts” be the time taken by the “S” wave, “tp” be the time taken by the “P” wave.

Given ts – tp = 16.2 s

Let distance travelled by them be “D”

Step 2

We can wri...
