One rotation of the carousel takes 12 seconds. How much faster does Maya travel than Kelly?

Maya travels   faster than Kelly !

Difference in distance is :

Step-by-step explanation:

Here we have , The Carousel in the National Mall has 4 rings of horses. Kelly is riding on the inner ring, which has a radius of 9 feet. Maya is riding on the outer ring, which is 8 feet farther out from the center than the inner ring is. We need to find In one rotation of the carousel, how much farther does Maya travel than Kelly . Let's find out:

Kelly is riding on the inner ring, which has a radius of 9 feet

Total distance traveled by Kelly is circumference of circle with radius 9 feet i.e.

⇒

⇒

⇒

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

So , Maya travels   faster than Kelly !
