The separation of P-waves and S-waves on a seismogram recorded 4500 km from the epicenter of an earthquake is six minutes. On another seismogram, that separation is seven minutes. Is the second station closer to or more distant from the epicenter?Explain.

Respuesta :

Answer:

It is further away

Explanation:

The first thing is to calculate the speed at which it moves:

4,500 km / 6 minutes = 750 km / min

which means that per minute the distance is 750 km away from the epicenter.

Now, they tell us that the other case took 8 minutes, knowing the speed, we calculated the distance, like this:

750 km / min * 7 min = 5250 km

Which means that it is further away since it is a value greater than 4500.
