The car did not travel at a constant speed, the total time for the trip was 50 minutes, it did not slow down, and it returned to its starting position.
In the given question, we have a graph of position versus time for the car's trip. Based on the graph, we can determine the following:
A. It did not travel at a constant speed for the entire trip: From the graph, we can see that the position versus time curve is not a straight line, indicating that the car's speed varied throughout the trip.
B. The total time for the car trip was 50 minutes: Looking at the x-axis of the graph, we can see that the total time elapsed is 50 minutes.
C. It did not slow down during the trip: Since the position versus time curve does not show any negative slope, it means that the car did not slow down during the trip.
D. It returned to where it had started at the end of the trip: The graph shows that the car's position at the end of the trip is the same as its starting position, indicating that it returned to where it had started.
