Sagot :
The time taken for the first p-wave to reach the same seismic station is approximately 13 minutes.
Time of travel of the P-wave
In rock, S waves generally travel about 60% the speed of P waves, and the S wave always arrives after the P wave.
Relationship between speed and time
v ∝ 1/t
v₁t₁ = v₂t₂
t₁/t₂ = v₂/v₁
t₁/t₂ = 0.6v₁/v₁
t₁/t₂ = 0.6
t₁ = 0.6t₂
t₁ = 0.6 x 22 mins
t₁ = 13.2 mins
Thus, the time taken for the first p-wave to reach the same seismic station is approximately 13 minutes.
