Once the hot air balloon reaches its cruising altitude, it flies at an elevation of 2,400 feet. It stays at its cruising altitude, meaning it does not ascend or descend, for 30 minutes.
The balloon is cruising at an elevation of 2,400 feet. That means it stays at a height of 2,400 feet above sea level and does not ascend or descend during this time. So 1 minute after reaching cruising altitude, it will still be at an elevation of 2,400 feet. Show this in the table.
