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.
