The temperature at 12 noon was 10° C above zero. 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 1

hange 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.

Step-by-step explanation:

hange 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.
