The graph below shows the distance and time traveled by a remote-controlled car.
Which of the following is correct about the remote-controlled car?
a
It is traveling at a constant speed of 12 meters per second.
b
It is traveling at an increasing speed of 6 meters per second.
c
It is traveling at an increasing speed of 12 meters per second.
d
It is traveling at a constant speed of 6 meters per second.
The correct answer is: d) It is traveling at a constant speed of 6 meters per second.
From the graph, we can see that the distance traveled by the car increases linearly with time, indicating a constant speed. The slope of the line represents the speed, and since it is constant throughout the entire graph, we can conclude that the car is traveling at a constant speed of 6 meters per second.
