Final answer:
The plane flies 1,000 miles in 2 hours.
Step-by-step explanation:
To determine how far the plane flies in 2 hours, we can set up a proportion using the given information. Since the plane flies 4,000 miles in 8 hours, we can write the proportion as 4,000 miles / 8 hours = x miles / 2 hours. To find x, we can cross multiply and solve for x: 8x = 4,000 * 2. Dividing both sides by 8, we get x = 1,000 miles. Therefore, the plane flies 1,000 miles in 2 hours.
