Question

If hurricane eric changed the temperature by -11 in 4 hours, how much did it change each hour?

a -44° b 44°

c 2.75° d -2.75°

Answer 1

-2.75 degrees

Explanation:

4 hours ----> Temp Changed by -11 degrees

1 hour ------> Temp changed by -11/4 = -2.75 degrees

Answer 2

-2.75°

Explanation:

Let it change x° each hour.

It has been given that hurricane Eric changed the temperature by -11 in 4 hours.

So, we have the below equation

`(-11)/(4)=(x)/(1)`

Solve the equation for x. Cross multiplying

`4x=-11`

Divide both sides by 4

`x=-(11)/(4)\\\\x=-2.75`

d is the correct answer.
