Johnson ran the 100 meter dash in 9.79 seconds. Calculate Johnson's average speed, in meters/second.
100/9.79 = 10.2 meters per second
To calculate Johnson's average speed, in meters/second, we need to divide the distance he ran (100 meters) by the time it took him (9.79 seconds).
Average Speed = Distance / Time
Therefore, Johnson's average speed in meters/second = 100 meters / 9.79 seconds.
To get the answer, we simply perform the calculation:
Average speed = 100 / 9.79 ≈ 10.214 meters/second
So, Johnson's average speed, rounded to three decimal places, is approximately 10.214 meters/second.
