Answer:
The present room temperature = 40\degree C40°C
The room temperature decreasing every hour by rate of = 5\degree C5°C
The room temperature after 10 hours will be
= 40\degree C\ +\ 10\times\left(-5\degree C\right)40°C + 10×(−5°C)
= 40\degree C-50\degree C\40°C−50°C
= -10\degree C−10°C
so, the room temperature after 10 hour = -10\degree C−10°C
