Question 240650: A thermometer that reads 80 degree C is brought into a room that is at 20 degree C. exactly three minutes later, it reads 70 degree C. when will it read 50 degree C? Answer by JimboP1977(308) (Show Source):
You can put this solution on YOUR website! 10 degree drop in three minutes. So 3 and 1/3 drop in 1 minute
30 degrees divided by 3 and 1/3 equals 9 minutes.
Not sure what logs have to do with this unless I am missing something obvious?
