Answer:
1234285.7 m or 1234.3 km
Explanation:
Let the distance be , the time taken by P waves be
and the time taken by the S waves be
.
For the P waves,
For the S waves,
Equating the ,
Divide both sides of the equation by 500 to reduce the terms.
Since S waves arrive 2 minutes (= 120 seconds) after P waves,
Substitute this in the equation of the distance.
Substitute this in the equation for involving
.
