Two large containersAandBof the same size are filled with different fluids. The fluids in containersAandBare maintained at 0C and 100C, respectively. A small metal bar, whose initial temperature is 100C, is lowered into containerA. After 1 minute the temperature of the bar is 90C. After 2 minutes (since being lowered into containerA) the bar is removed and instantly transferred into the other container. After 1 minute in containerBthe temperature of the bar rises 10. How long, measured from the start of the entire process, will it take the bar to reach99.4C? (Round your answer to two decimal places. Assume the final temperature being asked for is reached while the bar is containerB.)
