From the problem we get that:
The temperature at 12 noon is 10o C.
The rate of fall of temp. is 2oC per hour.
The total fall of temp. = 10oC to 0oC from 0oC to -8oC = 18oC
Since the temp. to fall 2o it takes 1 hour
The temp. to fall 18o the time taken will be 1/2 x 18 = 9 hours.
Since the present time is 12 noon and if it takes 9 hours to reach the temp. of -8oC.
Then the time at which the temp. will be -8oC = 9 pm in the night.
Since the temp. at 9 pm is -8oC, the temp at 12 midnight will be (12 - 9 = 3 Hours).
Since falls @ 2o per hour, in 3 hour it will fall = 3 x 2 = 6o.
Then the temp. at midnight will be -8oC + (-6oC) = -14oC.
The temperature at 12 noon is 10o C.
The rate of fall of temp. is 2oC per hour.
The total fall of temp. = 10oC to 0oC from 0oC to -8oC = 18oC
Since the temp. to fall 2o it takes 1 hour
The temp. to fall 18o the time taken will be 1/2 x 18 = 9 hours.
Since the present time is 12 noon and if it takes 9 hours to reach the temp. of -8oC.
Then the time at which the temp. will be -8oC = 9 pm in the night.
Since the temp. at 9 pm is -8oC, the temp at 12 midnight will be (12 - 9 = 3 Hours).
Since falls @ 2o per hour, in 3 hour it will fall = 3 x 2 = 6o.
Then the temp. at midnight will be -8oC + (-6oC) = -14oC.
