Review the graph below, which plots total distance traveled versus time of travel for a moving object. Why do the values on the graph form a straight line? A. The speed is constant. B. The distance remains unchanged. C. The direction of motion stays the same. D. The speed gradually increases over time.
A. The speed is constant.
The values on the graph form a straight line because the speed of the object is constant. This means that the object is traveling at the same speed throughout the entire duration of the time of travel, resulting in a linear relationship between total distance traveled and time. If the speed gradually increased over time, the graph would not form a straight line.
