To calculate Johnson's average speed in meters per second, we need to divide the distance he ran by the time it took him to complete the race.
Let's start by converting the time to seconds:
9.79 seconds
The distance covered in the 100-meter dash is 100 meters.
Now we can calculate the average speed:
Average Speed = Distance / Time
Average Speed = 100 meters / 9.79 seconds
Average Speed ≈ 10.22 meters per second
So, Johnson's average speed in the 100-meter dash is approximately 10.22 meters per second.
