the temperature at 12 noon was 10°c above 0 . if it decreases at the rate of 2°c per hour until midnight, at what time would the temperature be 8°c below zero? what would be the temperature at midnight |

Answer» Answer: Change in TEMPERATURE = 10 - ( -8 ) = 18°C. RATE of decrease = 2° per hour. Time = 18 / 2 = 9 hours. So, the time at which temperature goes 8°C below 0 is 9:00 PM. |
