You take 300 milligrams of headache medicine, and after 2 hours, 180 milligrams remain in your system. How long will it take from the time of the initial dose for the effects of the medicine to wear off, if this occurs when only 100 milligrams remain? (Assume the amount of medication in your system decays exponentially.) Round to the nearest hundredth of an hour.
