k. a student graphs the motion of a toy car. the student graphs the data from their investigation. which two statements describe the graph? circle your answer. motion of toy car a. the average speed of the toy car in this investigation is 3.33 m/s. b. the average speed of the toy car in this investigation is 0.3 m/s. c. the toy car speed decreases throughout the investigation. d. the toy car remains at a constant speed throughout the investigation. e. the toy car speed increases throughout the investigation.
Answer
# Answer:
C. The toy car speed decreases throughout the investigation.
# Explanation:
## Step1: Analyze the graph
The distance - time graph shows a curve where the slope is decreasing.
## Step2: Recall relationship between slope and speed
In a distance - time graph, the slope represents speed. A decreasing slope means decreasing speed. So, the speed of the toy car decreases throughout the investigation.
