For the above particle, if at t=0s, vx=-4 m/s, what is the velocity at t=20s?

With the same condition as in previous problem, what is the average velocity in time interval 0 to 20 s?

Yet still for the same setting, what is the average speed in time interval 0 to 20 s?

The answer for the average speed is 9.5 m/s not 9.1 m/s like the average velocity is and I can't firgure out why that is.
