Answer:
The horse walks 1,408 yards in 12 minutes.
Explanation:
To convert feet to yards, you can use the fact that 1 yard is equal to 3 feet. Therefore, to find out how many yards the horse walks in 4,224 feet, divide 4,224 by 3:
Number of yards = 4,224 feet / 3 feet/yard = 1,408 yards
So, the horse walks 1,408 yards in 12 minutes.
