The answer is: <u>Land Use</u>
You have to look at the arrival time between the P and S waves. it looks like they already did it for you here. the answer is 1035 km.
I drew a couple extra lines to show you in more detail.
Let's say for example our p-wave arrived at t=4min and our s wave arrived at t=6.5 min. The time difference is 2.5 min. So you can either plot 4 and 6.5 and draw a line straight across like I did (green line and dotted green) or find the spot where the distance between the two lines is t = 2.5 min. We see the epicentral distance for the green line is about 1800km.
Try the yellow line yourself. you should get t values of about 4.5 and 8.5 at an epicentral distance of 2600km.
The ozone layer and our thick atmosphere keep the earth insulated!! any heat we get from the sun stays on the earth, warming everything up, since the ozone layer acts almost like insulation (or a greenhouse). i hope this helps!!
