So, here's today's Assignment for you guys to solve.


There is a very strong radiation source in the center of a large 120 x 120 foot room. A person must run through this room to get to safety. Her escape route takes her the full lenth along one wall of the room. She is not exposed to radiation outside the room. The strength of the radiation is inversely proprtional to the square of her distance from the source. At 5- feet, her body is absorbing radiation at the rate of 200 un**** per second. If she runs at 12 feet per second, what is the tottal radiation dose she recieves during her dash to safety?


You must show the integral used to solve problem.
