A glass of milk is moved from a refrigerator with a temperature of 3"C to a room with a temperature of 20 C. One minute later the milk has warmed to a temperature of 6 C. Determine the temperature of the milk at time t. After how many minutes does the milk have a temperature that is 90% of the ambient temperature? Find the solution for the temperature at time t. T(t) = (Use integers or decimals for any numbers in the expression. Round to four decimal places as needed.) After approximately minutes, the milk will have a temperature that is 90% of the ambient temperature. (Do not round until the final answer. Then round to the nearest integer as needed.)
