The average velocity of the horse is 5.28 m/s.
The velocity is the rate of change of displacement with time.
The average velocity of an object is the ratio of total distance to total time of motion.
[tex]v = \frac{38 + \ 0.5(38)}{9 + 1.8} \\\\v = \frac{57 }{10.8} \\\\v = 5.28 \ m/s[/tex]
Thus, the average velocity of the horse is 5.28 m/s.
