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.
