A body whose temperature is 180°C is cooled by immersing in a liquid at 60°C. In one minute, the temperature of the body has fallen to 120° C. The rate at which the body temperature (7) change at time t is given by the equation T- -k(T-60). Calculate the time it take for the temperature of the body to fall to 90°C. dt
