Ans: Given : Temprature at 12:00 Noon = + 10^o C
Decrease rate = 2^o C per Hour

Temprature at 12:00 Noon = + 10^o C
Temprature at 1:00 PM = + 8^o C
Temprature at 2:00 PM = + 6^o C
Temprature at 3:00 PM = + 4^o C
Temprature at 4:00 PM = + 2^o C
Temprature at 5:00 PM = 0^o C
Temprature at 6:00 PM = - 2^o C
Temprature at 7:00 PM = - 4^o C
Temprature at 8:00 PM = - 6^o C
Temprature at 9:00 PM = - 8^o C

The temperature Will be -8^o C degree at 9:00 PM
