⇒
⇒
⇒
Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring .
Total distance traveled by Maya is circumference of circle with radius (8+9=17) feet i.e.
⇒
⇒
⇒
Therefore , Difference in distance is :
Now , Speed of both is give by
⇒ And ,
⇒
Faster Maya travels = 8.90-4.71 = 4.19
