14 degrees Fahrenheit not -16 saifoo.khan you're wrong. Since the temperature went down an average of 2 degrees every hour for 8 hours, it must have gone down by 16 degrees in total in the 8 hours and now the temperature is -2. Therefore, -2 + 16 = 14 So the temperature started off as 14 degrees Fahrenheit 8 hours before, went down by 2 degrees per hour for 8 hours or 16 degrees. To confirm the answer, 14-16 = -2.
