One degree at the Earth's surface is ∼111.19 km and u [s/deg] = u [s/km] g with In Figure 5 the time window around the P arrival is shown. The arrival times of P, PcP (the reflection at the core-mantle boundary), and PdP are shown.

Hence, the slowness of a P-wave in a material is inversely proportional to the strength of the material and directly proportional to the density of the material, i.e.; Strength and Strength r r V ∝ ∆t ∝ (16.2) The strength of a material is defined by two parameters (i) the bulk modulus, and (ii) the shear modulus.
Webslowness computed in this way may be slower than the true formation shear slowness, hence the need for a dispersion correction.
