Solve the problem.A fully cooked turkey is taken out of an oven set at 200°C (Celsius) and placed in a sink of chilled water of temperature 4°C. After 3 minutes, the temperature of the turkey is measured to be 50°C. How long (to the nearest minute) will it take for the temperature of the turkey to reach 15°C? Assume the cooling follows Newton's Law of Cooling: U = T + (Uo - T)ekt.(Round your answer to the nearest minute.)
