It is speeding up because more distance is covered every second.
Explanation:
The car can be described to be speeding up because more distance is covered every second.
From what we understand about velocity and acceleration, the car is accelerating through the ramp.
It's velocity is increasing with every second it covers.
This will invariable reduce the time between each distance covered.
Originally, the toy car starts with a low initial velocity or speed. As it gains acceleration, the speed will increase and more distance covered per seconds.
This is why the dots clustered towards the end of the diagram. The positions are getting closer and distance reducing per seconds.
