Speed of Sound in Air

Speed of Sound in Air problem 7

A longitudinal seismic wave propagates from the hypocenter of an earthquake at a speed of 8.2 km/s and a transverse one with a speed of 4.6 km/s. The longitudinal wave reaches the seismological measuring station 30 s earlier than the transverse one. How far from the measuring station is the hypocenter of the earthquake?
