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