To analyze the point at (1, 2) on the graph where the x-axis represents time in seconds and the y-axis represents distance traveled in feet, we can interpret what this point signifies.
The point (1, 2) indicates that at 1 second, the distance traveled by the train is 2 feet. Hence, this provides us with information about the train's position at a specific time.
From this, we can conclude that:
C. The distance traveled by the train increases from 1 foot to 2 feet in 1 second.
This is the best answer because it indicates that the train has traveled a distance of 2 feet at the 1-second mark.
However, the phrasing might imply that the train started at 1 foot, which we don't know from the provided point alone — we only know that at 1 second, it's at 2 feet.
The best understanding of point (1, 2) is simply that after 1 second, the train has traveled a total distance of 2 feet.
So, based on the options given, no option perfectly captures the precise meaning. However, A could be misleading because it suggests a continuous rate rather than a specific point in time. C is the closest despite the ambiguity of starting distance.
Therefore, I'd consider marking C as the best choice while being aware of its limitations.
