at 9:00 a.m. the temperature would be 8 Degrees Celsius below 0
and at midnight means 12 p.m. the temperature would be 14 degrees Celsius below zero
Step-by-step explanation:
to find what at what time temperature would be 8 degree Celsius below zero we would add 10 and 8 and then divide it by 2 to get time ,then we will get 9 . so, 9 hours after the temperature would be 8 degree Celsius below zero
and to find what temperature would be at midnight first we would calculate how much hours would be there. so 12 hour and to get how much temperature has decreased we will multiply it by 2 then 24 will come as answer we will add 10 + - 24 and ans is -14
