The graph shows the distance traveled by a model train going around a track.
The graph has time in seconds on the x-axis from 0 to 5 and distance in feet on the y-axis from 0 to 12. A straight line starts from (0, 0) and passes through (1, 2).
What can be concluded from the point 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.
