Question

The temperature at noon at a certain place is 8 degrees above zero. If it decreases at the rate of 2 degrees per
hour until midnight, at what time would the temperature be 6°C below zero? What would be the
temperature at midnight?​

Answer 1

Answer:

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 ...

Answer 2

Step-by-step explanation:

difference between the temperature 8°C above zero and 6°C below zero = 8-(-6)

= 14

time for this decrease = 14÷2 = 7 hours

so, the temperature 6°C below zero at 7 p.m.

difference between noon and midnight = 12 hours

decrease in the temperature in 12 hours = 12×2 = 24°C

so, the temperature at midnight = 10°C - 24°C

= -14°C
