Given:


Lauryn Williams had a reaction time of 0.214 second


Her total race of 100m time was 11.03 seconds


Formula UsedTheory:


Subtracting reaction time from total time gives


Actual time to cover the distance


Total race time of Lauryn Williams was 11.03seconds


The reaction time of Lauryn Williams was 0.214 seconds


Actual time taken to run 100m = 11.03-0.214seconds
