The graph below shows the distances in miles traveled by a helicopter in a certain number of hours. Based on the graph, which of the following equations indicates the correct variables, and in how many hours does the helicopter travel 3000 miles if it travels at the same speed? Graph titled Motion of a Helicopter shows Time in hours on x axis and Distance in miles on y axis. A straight line joins the ordered pairs 0, 0 and 2, 200 and 4, 400 and 6, 600.

x = 100y, the helicopter travels 3,000 miles in 32 hours
y = 100x, the helicopter travels 3,000 miles in 30 hours
y = 100x, the helicopter travels 3,000 miles in 32 hours
x = 100y, the helicopter travels 3,000 miles in 30 hour
