Answer:
2 hours
Explanation:
We are given a position time graph.
Position time graph is any graph from which we get the relationship between distance and time.
The slope obtained can be used to find the speed of the car.
By studying the graph, it is seen at displacement of 40 km,the car took 2 hours as seen on x-axis.
Just see the graph where the exact point is located and see x and y-axis.
Hence,the car took 2 hours.
