When an earthquake occurs, two types of sound waves are generated and travel through the earth. The primary, or P, wave has a speed of about 8.0 km/s and the secondary, or S, wave has a speed of about 4.5 km/s. A seismograph, located some distance away, records the arrival of the P wave and then, 88.7 s later, records the arrival of the S wave. Assuming that the waves travel in a straight line, how far (in terms of m) is the seismograph from the earthquake?(adsbygoogle = window.adsbygoogle || []).push({});

I really don't know how to approach this problem

We skipped around chapter wise and I think I'm missing some important information from previous chapters regarding this problem.

The only logical equation that I think might be applicable to this problem is v = sqrt(ykT/M). Are there some crucial givens that I'm over looking?

I really just need some hints as to how to approach this problem

Thanks a lot
