An earthquake originated in New York State. The P-wave travel time for this earthquake was recorded in the data table below for four widely separated seismic stations, A, B, C, and D If the first P-wave arrived at seismic station A at 10hrs:22min:30sec, what was the origin time for the earthquake?

The provided question is incomplete as it lacks the essential information to give answer. however, the complete question is attached as image.

The correct answer is option :  c. 10hrs: 14min: 10sec.

Explanation:

The question provides the following information to answer the question:

The P wave takes time to reach Seismic station A = 8 min:20 sec

P-wave arrived at seismic station A at : 10hrs:22min:30sec

So, the origin time of earthquake would be: 10hrs:22min:30sec - 8 min:20 sec = 10hrs: 14min: 10sec.

Thus, the correct answer is :  10hrs: 14min: 10sec.
