A Correct answer
Explanation

Speed = 185 km/hr = 185 * (1000/3600) m/s = 185 * (5/18) m/s = 51.388 m/s. Distance = 51.388 * 11 = 565.277 m.

AI explanation

First, convert the speed from km/hr to m/s using the conversion factor of 5/18, making the speed 185 multiplied by 5/18, which equals 51.388 m/s. Using the distance formula, distance equals speed multiplied by time, we multiply 51.388 m/s by 11 seconds. This gives a total distance of 565.27 m, which rounds to 565.28 m.
