Question

On Monday the temperature is 76 degrees but by Friday the temperature has increased to 86 degrees. What is the average rate of change (per day) of the temperature from Monday to Friday?

Answer 1

Average rate of change per day from Monday to Friday = 2.5 degrees per day

Step-by-step explanation

The average rate of change of any quantity with respect to time (per day) is given as

`\text{Average rate of change = }\frac{(New\text{ value) - (}Old\text{ value)}}{Number\text{ of days}}`

For this question,

New value = Temperature on Friday = 86 degrees

Old value = Temperature on Monday = 76 degrees

Number of days from Monday to Friday = 4 days

`\begin{gathered} \text{Average rate of change = }\frac{(New\text{ value) - (}Old\text{ value)}}{Number\text{ of days}} \\ \text{Average rate of change = }(86-76)/(4) \\ =(10)/(4) \\ =2.5\text{ degr}ees\text{ per day} \end{gathered}`

Hope this Helps!!!
