Question 730258: Radiation machines, used to treat tumors, produce an intensity of radiation that varies inversely as the square of the distance from the machine. At 3 meters, the radiation intensity is 62.5 milliroentgens per hour. What is the intensity at a distance of 1.6 meters? (Round to nearest tenth.)
I think I am supposed to use inverse variation formula y=k/x but I have no idea how to even set the problem up. Thanks for any help.
