While riding a chairlift, a 55 kg skier is raised a vertical distance of 370 m. what is the total change in the skier's gravitional potential energy?

given:

m = 55 kg

d = 370 m

When i used PE = mgh, the answer was 199,430, i know its wrong since the answer is something else. But what equation can i use?
