Question 1140000: Can someone help me solve the following word trigonometric problem here? here's the problem regarding linear speeds on a carousel:
"A carousel has two circular
rings of horses. The inner ring has a radius of 14.5 feet and the
outer ring has a radius of 21.0 feet. The carousel makes one com-
plete revolution every 24 seconds. How much greater, in feet per
second, is the linear speed of a horse in the outer ring than the
linear speed of a horse in the inner ring? Round to the nearest
tenth of a foot per second."
Thanks in advance!

You can put this solution on YOUR website! "A carousel has two circular

outer ring has a radius of 21.0 feet. The carousel makes one com-
plete revolution every 24 seconds. How much greater, in feet per
second, is the linear speed of a horse in the outer ring than the
linear speed of a horse in the inner ring? Round to the nearest
tenth of a foot per second."
----------
The rings moves their circumference in 25 seconds.
---
Inner: 2*pi*14.5/24 ft/sec
Outer: 2*pi*21/24 ft/sec
-------------
Calculate, subtract.
