Question

The graph shows the relationship between the time and the speed of a train that has already left the station. During which time period was the train traveling at a constant speed? A. between o and 20 minutes B. between 20 and 40 minutes C. between 40 and 60 minutes D. between 60 and 80 minutes

Answer 1

To answer this question, we need to look at the points on the graph where the speed of the train does not change over time. This would be represented by a horizontal line on the graph.Step 1: Look at the points given and determine where the speed (y-coordinate) remains the same for different times (x-coordinate).The points given are (0, 40), (20, 60), (40, 50), (60, 50), (80, 60), and (100, 40).Step 2: Identify the time periods where the speed remains constant.From the points, we can see that the speed remains constant between the time periods (40, 50) and (60, 50). This means the speed of the train did not change between 40 and 60 minutes.So, the answer is C. between 40 and 60 minutes.
