Question

Your friend tells you that at 1:00 pm the temperature outside was 67 degrees Fahrenheit and at 5:00 pm, that same day, the temperature was 65 degrees Fahrenheit. He also states that the average rate of change of the temperature between 1:00 pm and 5:00 pm increased by 2 degrees Fahrenheit. Determine if your friend is correct and explain why or why not.

Answer 1

He is wrong because the temperature decreased by 2 degrees fahrenheit from 67 degrees fahrenheit to 65 degrees fahrenheit not increased

Answer 2

Answer: No, my friend is not correct here.

Step-by-step explanation: One of my friends told me that -

At 1:00 pm, the outside temperature was 67 degrees, and

at 5:00 pm, the outside temperature was 65 degrees.

Therefore, the average rate of change of the temperature between 1:00 pm and 5:00 pm

=65 - 67

= -2 degrees.

That is, there is a decrease of 2 degrees in the temperature between 1:00 pm and 5:00 pm. But, my friend told me that temperature was increased by 2 degrees. So, my friend is not correct.
