B Correct answer
Explanation

Using s = d/t, s = 135 / 10 = 13.5 m/s.

AI explanation

Using the given speed, distance, and time formula s = d / t, we substitute the known values. The distance is 135 meters and the time is 10 seconds, so s = 135 / 10. This calculation yields a speed of 13.5 m/s. The result is 13.5 m/s.
