Answer:
Ethan's tangential speed is twice as Rebecca's.
Explanation:
Let 
be the distance from the center of the platform to Rebecca's horse, 
Rebecca's tangential speed, 
the Ethan's tangential speed and 
the merry-go-round angular speed. The distance from the center of the platform to Ethan's horse is 
. The angular speed is related to the tangential speed by the equation:
Since the angular speed is the same for Ethan and Rebecca, we have that:
Now, solving for we get:
It means that Ethan's tangential speed is twice as Rebecca's.
