c. In 2 seconds, the commuter train travels 120 feet.
Step-by-step explanation:
Given
The attached graph
Required
What does x-coordinate of 2 represents
Represent this coordinate with (x,y)
From the graph:
[tex]x = 2[/tex] when [tex]y = 120[/tex]
Note that:
x = time and y = distance
So:
[tex](x,y) = (2,120)[/tex]
Which means:
At 2 seconds, the train has travelled a distance of 120ft
From the list of options, (c) is correct
