du Newton's law of cooling is- = -k(u-T), where u(r) is the temperature of an object, r is in hours, T' is a constant ambient dt temperature, and k is a positive constant. Suppose a building loses heat in accordance with Newton's law of cooling. Suppose that the rate constant khas the value 0.13 hr-¹. Assume that the interior temperature is 7, = 72°F, when the heating system fails. If the external temperature is T = 11°F, how long will it take for the interior temperature to fall to 7₁ = 32°F? Round your answer to two decimal places. The interior temperature will fall to 32°F in ! hours.
