Require that
T(delay) = 55.9 s = D/5.08 - D/8.3312
= 0.07682 D
D = 727.7 km
The velocity of the transverse waves produced
by an earthquake is 5.08 km/s, while that of
the longitudinal waves is 8.3312 km/s. A seismograph records the arrival of the transverse
waves 55.9 s after that of the longitudinal
waves.
How far away was the earthquake?
Answer in units of km.
