Answer:
D. It travels for 2 hours, then stops for 1 hour, and finally travels again for 2 hours.
Step-by-step explanation:
From the pair (0, 0) to (2, 26), we can see over a period of two hours, the car moved 26 miles, as the distance went from 0 to 26.
From the pair (2, 26) to (3, 26), we can see over the course of an hour, the car maintained the same distance, 26 miles, the entire time. This means that it stopped. We can rule out options A and B since those include a stop of 3 hours, when the stop is actually only 1.
From the pair (3, 26) to (5, 52), we can see over a time period of 2 hours, the car moved from 26 to 52 miles, so in other words it travelled. We can rule out C because the car only travelled 2 hours, from hour 3 to hour 5.
This leaves us with D as the answer, which perfectly fits the graph.
