Expert Answer:

Time, t = 1 s
Displacement AB is the diameter of the semicircle i.e., 2 m.
begin mathsize 14px style Average space velocity equals Displacement over Time equals AB over straight t equals fraction numerator 2 space straight m over denominator 1 space straight s end fraction equals 2 space straight m space straight s to the power of negative 1 end exponent end style
The average velocity is 2 m s-1.
