How long after receiving the first P-wave froman earthquake centered 4000 kilometers awaydoes a seismic station receive its first S-wavefrom the same earthquake?
A
1 minute
B
5 minutes 35 seconds
C
7 minutes
D
12 minutes 40 seconds
Explanation: 

Detailed explanation-1: -How long after receiving the first P-wave from an earthquake centered 4000 kilometers away does a seismic station receive its first S-wave from the same earthquake? A P-wave takes 5 minutes to travel from the epicenter of an earthquake to a seismic station.

Detailed explanation-2: -For example, this graph tells you that if an earthquake epicenter is 4000 km away, the P-wave will take 7 minutes to get to you.

Detailed explanation-3: -How long would it take for the first S-wave to arrive at a seismic station 4, 000 kilometers away from the epicenter of an earthquake? 12 min. 40 sec. How far will a S-wave travel in 10 minutes and 40 seconds?

Detailed explanation-4: -Seismic station A is shown on Earth’s surface. At station A, the first P-wave arrives 11 minutes 40 seconds after the earthquake.

Detailed explanation-5: -5 minutes and 40 seconds. seismic station. time (5:40) to the P wave line. 3000 kilometers!
