Answer:
speed = 8.57mph while v = 0 mph
Explanation:
The horse is running 1 mile in 7 minutes. Then for a total of 1 hour, 60 minutes, the horse should be able to run a distance of
[tex]\frac{1*60}{7} = \frac{60}{7} = 8.57mph[/tex]
So the horse speed is 8.57 miles per 60 minutes, or 8.57 mph (mile per hour). But if he ends up at the same point as before int he oval track, one can argue that the displacement is 0, and so is its velocity.
