Question

At 3p.M the temperature is 12 f it then began to drop 2f every hour for 7 hours what is the temperature after 7 hours

Answer 1

The temperature after 7 hours is -2° F

Explanation

At 3 p.m the temperature was 12° F

Then , the temperature began to drop 2° F every hour.

So, the total temperature dropped in 7 hours will be:  $(2*7)=14$° F

Now, for finding the temperature after 7 hours, we need to subtract the "temperature dropped" from the "initial temperature".

Thus, the temperature after 7 hours $=12-14= -2$° F
