Mach 3.5 about 2600 mph
The SR-71 Blackbird is 2,193 miles per hour fast or Mach 3, three times faster than the speed of sound.
(2,193 mph) from what I know this is the spy plane we are talking about right?
The time it would take a blackbird to fly around the Earth depends on its speed and the distance to cover. A blackbird can fly at speeds of about 20 to 30 miles per hour. The Earth's circumference at the equator is approximately 24,901 miles. At an average speed of 25 miles per hour, it would take the blackbird around 1,000 hours, or about 41.7 days, to complete the journey without resting.
The Lockheed-Martin SR-71 Blackbird's top speed was Mach 3.5, or 3.5 times the speed of sound. that is 2664 miles per hour and 4287 kilometres per hour
The SR-71 Blackbird has been clocked at over 2,200 miles per hour.
The absolute top speed remains classified. Officially "in excess of Mach 3" Probably closer to Mach 3.5 - 3.8
The top speed of an SR-71a "Blackbird" is 1,740 knots (2,000 miles per hour or 3,220 kilometers per hour). It had a maximum range of 2,900 miles (4,669 kilometers) without refueling and a flight ceiling (maximum altitude) of 85,000 feet (25,907 meters).
With an air-breathing engine, proably the SR-71 blackbird at more than 3,000 miles per hour
It depends on the plane. A commercial airliner cruises at a little over 500 mph. Military fighter jets can speed at 1400mph. The SR71B Blackbird survelince plane could go over 3000mph.
The SR-71 Blackbird is 2,193 miles per hour fast or Mach 3, three times faster than the speed of sound.
To convert 18,000 miles per hour to miles per second, divide the rate by the number of seconds in an hour. Since there are 3,600 seconds in an hour (60 seconds per minute multiplied by 60 minutes per hour), you calculate: 18,000 miles per hour ÷ 3,600 seconds per hour = 5 miles per second. Therefore, 18,000 miles per hour is equivalent to 5 miles per second.
22 minutes * (1 hour / 60 minutes) * (65 miles / 1 hour) = 23.833 miles.
