Yes, AI gave wrong answer but then corrected it.
AI Overview



An Airbus can cover 11 miles in approximately 10 to 11 seconds, as most jet airliners cruise at about 450 knots (approximately 518 mph or 740 ft/sec). 
Here's how to calculate it:
Find the speed in feet per second:
A typical cruise speed is 450 knots.
1 knot is about 1.68781 feet per second.
So, 450 knots * 1.68781 ft/sec/knot ≈ 759.51 ft/sec.
Convert the distance to feet:
11 miles * 5280 feet/mile = 58,080 feet.
Calculate the time:
Time = Distance / Speed.
Time = 58,080 feet / 759.51 ft/sec ≈ 76.47 seconds.
Note: The speed used in the initial result was 740 ft/sec, which would yield approximately 11 miles in about 11 seconds. Using the 450 knot figure, it's closer to 76 seconds. 
Therefore, at a typical cruising speed, an Airbus would take around 76 seconds to travel 11 miles.
