The height of a point on the graph corresponds to a speed on the y-axis.

-- As time goes on, the line for Car-A gets higher. Car-A is speeding up.

-- As time goes on, the line for Car-C gets lower. Car-C is slowing down.

-- As time goes on, the height of the line for Car-B doesn't change. Car-B is maintaining a constant speed.

In the given graph, car A is speeding up, Car C is slowing down and car B is maintaining a constant speed with time.

From the given graph we can deduce the following about the change in the speed of the cars with time.

  • The car A is speeding up because the change in speed of the car is increasing with time.
  • The car C is slowing down because the change in speed of the car is decreasing with time.
  • The car B is maintaining a constant speed because the speed of the car is not changing with time.

Thus, we can conclude the following from the given graph, car A is speeding up, Car C is slowing down and car B is maintaining a constant speed with time.
