Question

The temperature at 12 noon
was 10°C above
zero.
If it decreases 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

Answer:

Time = 18 / 2 = 9 hours. So, the time at which temperature goes 8°C below 0 is 9:00 PM. Also, The temperature at 12 :00 PM = 10° C, As temperature decreases at 2°C, Temperature at mid night = 10° C - 2 ( 12 ) = 10 - 24 = -14° C.
