Question

The temperature at 12 noon was 15°C above zero. If it decreases at 2°C per hour until midnight. What would be the temperature at midnight?

Answer 1

Answer:

12degree calcius hoga

Answer 2

Answer:

-9°C

Step-by-step explanation:

hrs from 12 noon to midnight = 12 hrs

decrease rate = 2 ° C/ hr

so decrease in 12 hrs = 2°C* 12

                                   = 24°C

temperature at midnight = 15°C - 24°C

                                       =  -9°C
