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:
Saint-Domingue (Haiti) was prosperous because of revenue earned from sugar.
Explanation:
When the Europeans came to Haiti, the native people lived in a simple way and were relatively isolated from their surroundings, let alone the world. The Europeans though thought that this place has big potential, especially in farming. What the Europeans had on mind was to create large plantations with sugar cane, thus produce sugar and make a profit out of it.
While the Europeans were not many in number, and the native population was decimated, a lot of African slaves were brought as a labor force for the plantations. The wet tropical climate enabled high-scale production of sugar cane, and with sugar becoming increasingly popular and being paid well for, the Europeans earned a lot from the trade. Haiti actually became a very prosperous island, and that was strictly down to the production of sugar cane and sugar from it.

Oxygen causes the chemical weathering of a rock containing iron to become soft and crumbly and reddish brown in color.
<h3>What is the role of oxygen in rock weathering?</h3>
Oxygen is said to be a very reactive element and this often makes it reacts with rocks and this often leads to rust formation and others.
Therefore, Oxygen causes the chemical weathering of a rock containing iron to become soft and crumbly and reddish brown in color.
