Answer: Teperature at 5PM will be 28°C
Ok so at 12 its 38°C
And it dcreases at 2°C an hour, we need to find the teperature at 5 o clock.
The number of hours between 12 and 5 mutiplied by 2 will give us the trail in temperature and then subtracting the trail i temperature witht the temperature a 12 will give us the teperature at 5 o clock.
SO,
hours between 12 PM and 5 PM is 5 hours
As, the temperature decreases at a uniform rate of 2°c per hour
⇒5×2°C
⇒10°C
Now the temperature at 5 PM will be 38°C-10°C=28°C
