Question

A chemistry student mixes two solutions to study the properties of the resulting mixture. The temperature of the new solution is given by the function T = 24t – 2t^2 + 5, where T is the temperature in degrees Celsius and t is the time elapsed in seconds after the solutions are mixed. What is the time interval that the temperature of the solution will be at least 69°C?
