Question

How far will a P-wave travel in 9 min 20 sec?

Answer 1

Since a P-wave can travel anywhere between 1.5 and 8 kilometers per second, then it is all a matter of multiply those numbers by how many seconds there are in total in 9 minutes and 20 seconds. If that is the case, then a P-wave will travel at least 840 kilometers in the said time frame.
