Answer:
- constant speed
- stopped
- slowing
Explanation:
You recall the relation between speed, distance, and time is ...
speed = distance / time
The graph is of distance vs. time. that means speed is the slope (distance/time) of the curve on the graph. If the slope is zero (a horizontal line), distance is not changing, and the speed is zero. That is, the vehicle has stopped.
If the slope is a positive constant, the vehicle is traveling at a constant speed.
If the slope is high, but becoming lower as the curve progresses left-to-right, then the speed starts high, but becomes lower: the vehicle is slowing down.
__
The graphs, left-to-right, represent a vehicle that is ...
traveling at constant speed
stopped
slowing down
