Two large containers A and B of the same sizeare filled with different fluids. The fluids in containersA and B are maintained at 0° C and 100° C,respectively. A small metal bar, whose initial temperature is 100°C, is lowered into container A. After 1 minute thetemperature of the bar is 90° C. After 2 minutes (since beinglowered into container A) the bar is removed and instantlytransferred into the other container. After 1 minute in containerB the temperature of the bar rises 10°. How long, measuredfrom the start of the entire process, will it take the bar to reach99.7° C? (Round your answer to two decimal places. Assume the finaltemperature being asked for is reached while the bar is containerB.)
