Hurrah, we come to the end of the module! We began the module talking about reaction time. The reaction time is the time between your eyes seeing something and your body reacting to it.
In this module, we discussed how to calculate the reaction time using a ruler in very simple experiment. Also, this is why you should not ride/drive very fast, especially if there is a vehicle in front of you.
If you are going very fast, even if your reaction time is low, your vehicle will travel enough distance to crash into the vehicle in front of you. So, when you start riding/driving, do it at safe speeds!
