1 knot = 1.151 mph
Therefore, to find how much faster an airplane is than a car, we need to divide the airplane's speed in knots by the car's speed in mph and then multiply by 100.
For example, if an airplane is flying at 500 knots and a car is traveling at 60 mph, then the airplane is approximately 833% faster than the car.
(500 knots / 60 mph) * 100 = 833.33%
This means that the airplane is traveling at a speed that is 8.33 times greater than the speed of the car.
