Answer:
If the average speed of s-waves is assumed, 4km/sec, then the time of arrival would be 02:11:57
Step-by-step explanation:
It is not possible to determine the exact time that the S-wave from an earthquake would arrive at a seismic station 9,000 km away based on the information provided. The speed at which seismic waves travel through the Earth's crust can vary depending on the type of wave and the composition of the rock and soil through which it is passing. In general, however, S-waves (also known as secondary waves) travel at a slower speed than P-waves (also known as primary waves), so it would take longer for the S-wave from an earthquake to reach a seismic station located 9,000 km away. Additionally, the distance and direction of the seismic station from the earthquake's epicenter would also affect the arrival time of the S-wave. To determine the exact arrival time of the S-wave, it would be necessary to have more detailed information about the earthquake, the composition of the Earth's crust in the area, and the specific location of the seismic station.
We can use the average though.
Important:
If you were given a number for the speed of the s-waves that you did not share here, then to find the time, do the following:
9,000 ÷ time (In the case of 4km/sec, do 9000 ÷ 4)
Divide the result by 60. You now have the minutes it takes.
Add the result to 02:11:20.
