Question

The temperature at noon was -16 F. For the next 6 hours it dropped at a rate of 4 degrees an hour. What is the temperature at 6 p.m.

Answer 1

The temperature at 6 p.m is -40 F.

Solution:

The temperature at noon is -16 F.

we have been asked to find the temperature at 6 p.m.

We know that the temperature is dropping at a rate of 4 F per hour.

That means is 6 hours it would have dropped

6
`*` 4 = 24 F.

So the amount of temperature dropped after 6 hours at the rate of 4 F per hour is 24 F.

But we know that the temperature at 12 pm is -16 F. so at 6 p.m the temperature will be.

-16 - 24 = -40 F.

So the temperature at 6 p.m is -40 F.
