Coroners estimate time of death using the rule of thumb that a body cools about 2°F during the first hour after death and about 1°F for each additional hour. Assuming an air temperature of 68°F and a living body temperatureof 98.6°F, the temperature T() in °F of a body at a time thours since death is given by T() = 68 + 30.6-¹ (a) For what value of k will the body cool by 2.1°F in the first hour? Round to three decimal places. 0.068 (b) Using the value of k found in part (a), after how many hours will the temperature of the body be decreasing at a rate of 1°F per hour? Round to one decimal place. hours
