An object is moving in a straight line (the x-axis). The graph in figure shows the x-coordinate of this object as a function of time. Which one of the following statements about this object is correct?
O A. Between points A and B, the x-component of its average velocity is 0.75 m/s, but its average speed is greater than 0.75 m/s.
O B. Between points A and B, both the x-component of its average velocity and its average speed are greater than 0.75 m's.
OC. Between points A and B, both the x-component of its average velocity and its average speed are less than 0.75 m/s.
O D. Between points A and B, the x-component of its average velocity is 0.75 m/s, but its average speed is less than 0.75 m/s.
O E. Between points A and B, both the x-component of its average velocity and its average speed are equal to 0.75 m's.
