A seismic monitoring station records P waves travelling through a layer of rock.
| Measurement | Value |
|---|---|
| number of complete oscillations | 24 |
| time for these oscillations | 6.0 s |
| distance from the first compression to the seventh consecutive compression | 5400 m |
The waves then enter a second layer of rock, where their speed is 25% greater.
Calculate the speed of the waves in the second layer of rock.
