Question 1200888: the intensity of the radiation used to treat a tumor varies inversely as the square of the distance from that emits the radiation. if the intensity is 100 milliroentgens per hour at a distance of 2.5 meters, at what distance is the intensity 39.0625 mr/h?

-----------------------------------------------------------------------
the intensity of the radiation used to treat a tumor varies inversely as the square of the distance from that emits the radiation.
---------------------------------------------------------------------

d, distance
I, intensity
k, variation constant

I=k%2Fd%5E2

Your given values for the question:
I=100
d=2.5
k, you find this value from the formula. Then use it to find some unknown d for the desired I=39.0625.
