To use the chart: Start at Ketchikan. The distance to the first stop (Juneau) is 224 miles. The distance between Juneau and Anchorage is 505 miles. The distance between Anchorage and Bethel is 340 miles and so on until you return to Ketchikan from Fairbanks.
The Wright Flyer was the first heavier-than-air powered airplane to fly successfully. It flew for 12 seconds, covering 120 feet. The Flyer was 21 feet, 1 inch long, weighted 746 pounds, and had a wingspan of 40 feet, 4 inches. The SR-71 Blackbird was a high-altitude, high-speed military reconnaissance plane. It set a work speed record in 1976, flying 2,193.7 miles per hour at 85,000 feet. The SR-71 was 107 feet, 4 inches long, weighed 67,550 pounds (without fuel), and had a wingspan of 55 feet 6 inches. Compare the length, weight, and wing span of the two planes and answer the following questions.
If the SR-71 flew 15,000 miles in ten and one-half hours, what would be the average airspeed (in miles per hour)?
The SR-71 surveyed 723,042.6 square miles of the United States in one hour.
