Physics - Sound Wave Question with Solution | TestHub

An earthquake generates both transverse$\left(\mathrm{S}\right)$and longitudinal$\left(\mathrm{P}\right)$sound waves in the earth. The speed of$\mathrm{S}$waves is about$6 \mathrm{km} {\mathrm{s}}^{-1}$and that of$\mathrm{P}$waves is about$9 \mathrm{km} {\mathrm{s}}^{-1}$. A seismograph records$\mathrm{P}$and$\mathrm{S}$waves from an earthquake. The first$\mathrm{P}$wave arrives$5$minute before the first$\mathrm{S}$wave. The epicenter of the earthquake is located at a distance of about -
