Question

question 10 of 15
this graph shows how fast a commuter train travels on its route in an urban area.
what is the meaning of the point with an x - coordinate of 4?
speed of
commuter train

a. the commuter train travels 4 feet in 240 seconds.
b. it takes the commuter train 60 seconds to go 4 feet.
c. in 4 seconds, the commuter train travels 240 feet.
d. in 1 second, the commuter train travels 4 feet.

Explanation:

Step1: Analyze the graph axes

The x - axis represents time (in seconds) and the y - axis represents distance (in feet).

Step2: Interpret the coordinate

A point \((x,y)\) on the graph means that in \(x\) seconds, the train travels \(y\) feet. When \(x = 4\) (the x - coordinate is 4), we find the corresponding \(y\) value. Looking at the graph, when \(x=4\), \(y = 240\). So it means in 4 seconds, the commuter train travels 240 feet.

Answer:

C. In 4 seconds, the commuter train travels 240 feet.
