Question 299092: This word problem is from the section of the chapter dealing with: Inverse and Joint Variation (Please solve showing steps)
The time it takes to get a sunburn varies inversely as the UV rating. At a UV rating of 6 the time it takes to obtain a sunburn can be as little as 15 minutes. Determine the time it will take to get a sunburn when the UV rating is 10.

The time it takes to get a sunburn varies inversely as the UV rating. At a UV rating of 6 the time it takes to obtain a sunburn can be as little as 15 minutes. Determine the time it will take to get a sunburn when the UV rating is 10.
-----------------
t = k/"uv"
----
Find "k" if t = 15 when uv= 6
15 = k/6
k = 90
------
General Equation for this problem;
t = 90/"uv"
---
Determine the time it will take to get a sunburn when the UV rating is 10.
t(10) = 90/10
time = 9 minutes
