Answer:
Hourly rate of temperature is [tex]-5\° F[/tex].
Step-by-step explanation:
Given;
Temperature dropped from 1pm-7pm = -30 F
Number of hours = 6
Also Given:
Temperature change every hour was the same.
We need to find the hourly rate of change.
Solution:
Now we know that;
In 6 hours = -30 F temperature changed
So in 1 hour = temperature changed in 1 hour.
By using Unitary method we get;
temperature changed in 1 hour = [tex]\frac{-30}{6}=-5\° F[/tex]
Hence Hourly rate of temperature is [tex]-5\° F[/tex].
