Answer 2

Explanation:

Given An epicenter station is 4,000 km away. How long after the first P-wave did the first S-wave arrive?

• So we have the epicenter station is 4000 km away. We need to find the time difference.
• So we have
• Time difference = d x t / 100 km
•                          = 4000 km x 8 s / 100 km
•                          = 32000 km x s / 100 km
•                          = 320 secs
• Therefore after the arrival of the first p-wave the first s-wave will arrive in 320 secs
