The concentration of a drug in a patient's bloodstream t minutes after an oral dose was administered was approximately C(t) = 0.7t(0.98t ), where C(t) was measured in micrograms per milliliter (µg/mL). Find the rate at which the drug concentration was decreasing two hours after the dose was taken. (Round your answer to four decimal places.)
