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.
Answer: Here's your answer!!
1)The responsible development of oil sands is a key driver of Alberta's and Canada's economy. It creates jobs and tax revenue for the government which supports the social programs and capital infrastructure projects we rely on.
2)Crude oil derived from the oil sands is refined into products, such as gasoline, diesel, and aviation fuel, which keep us warm, power our industries, and help us move about the country and the world (not to mention cooking those turkeys). With conventional oil supply declining, the need for oil sands is increasing.
3)A strong oil sands sector drives a strong national economy by attracting capital, creating jobs, and supporting public services. ... Local companies in every province supply goods and services to the oil sands—creating jobs, growth and economic opportunity in local communities!
Hope its helpful!
