The line segments show intervals where the distance remained constant are Segment 3, Segment 7, Segment 8
Based on the graph, we can see that the distance remained constant during the following intervals:
Segment 8: 12pm - 1pm
Segment 3: 10am - 11am
Segment 7: 2pm - 5pm
Therefore, the line segments that show intervals where the distance remained constant are:
Segment 3
Segment 7
Segment 8
Correct answer: Segment 3, Segment 7, Segment 8
