What can be concluded from the point (1, 2) on the graph?

A.
The distance traveled by the train increases at a rate of 2 feet per second.
B.
The distance traveled by the train increases at a rate of

foot per second.
C.
The distance traveled by the train increases from 1 foot to 2 feet in 1 second.
D.
The distance traveled by the train increases from 1 foot to 2 feet in 2 seconds.

None of the conclusions listed seems to be accurately inferred from the given point (1,2) alone. The point simply tells us that at a certain time (perhaps t = 1 second), the train had traveled 1 foot and was at a distance of 2 feet from the starting point. It does not give us information about the rate of change of distance or time. Therefore, the answer is E. None of the above.
