Answer:In both graphs, speed will be measured in meters/second.
In graph A, the object travelled a distance of 40 meters in 4 seconds
In graph B, the object is at rest for 5 seconds.
In both graphs A and B, the speed will be measured in meters/second because both graph shows the distance at one side and time on another side which is required for determining speed. In graph A, the object travelled a distance of 40 meters in 4 seconds due to moving with the speed of 10 meters in one second.
In graph B, the object is at rest for 5 seconds after achieving 25 meters in 5 seconds. The object in graph B was moving at a lower speed than the object in graph A i.e. in graph A the object moves 10 meters in one second whereas in graph B the object moves 5 meters in one second.
