1.	the temperature recorded at 12 noon was 15 degrees above zero if it decreases at rate of 3 degree Celsius per hour until midnight at what time will the temperature be 9 degree Celsius before 0 and what would be the temperature at midnight
Answer» Answer:8 pm. Step-by-step EXPLANATION:As it decreases by a constant rate we can easily find the TIME in which the temperature was -9°Celsius. Difference between starting and ending temperature=15-(-9)=15+9=24°Celsius So the temperature decreases by 24 degrees . As it REDUCES by 3 degrees each HOUR, the number of HOURS =24/3=8 hours Therefore the time at which it was -9°Celsius= 8 hours after 12 noon =8 pm.

the temperature recorded at 12 noon was 15 degrees above zero if it decreases at rate of 3 degree Celsius per hour until midnight at what time will the temperature be 9 degree Celsius before 0 and what would be the temperature at midnight

Answer:8 pm.

Step-by-step EXPLANATION:As it decreases by a constant rate we can easily find the TIME in which the temperature was -9°Celsius.

Difference between starting and ending temperature=15-(-9)=15+9=24°Celsius

So the temperature decreases by 24 degrees . As it REDUCES by 3 degrees each HOUR, the number of HOURS =24/3=8 hours
