Question

If a P-Wave took 5 minutes to reach a seismic

station and the earthquake began at 4:23:05, what
time did the P Wave reach the station?

Answer 1

Answer: 4:28:05

Explanation: if it takes 5 minutes to reach a station, just add 5 to the amount of minutes you already have (23) to get 28. And the hour and seconds stay the same.
