shelleys cup of tea cooled down $\frac{1}{2}$ of a degree in 10 seconds. at what rate is her tea cooling down? simplify your answer and write it as a proper fraction, mixed number, or whole number. degrees per second

Answer

Explanation:

Step1: Recall rate - formula

Rate = $\frac{\text{Change in quantity}}{\text{Change in time}}$

Step2: Identify values

Change in temperature = $\frac{1}{2}$ degree, change in time = 10 seconds.

Step3: Calculate the rate

Rate = $\frac{\frac{1}{2}}{10}=\frac{1}{2}\times\frac{1}{10}=\frac{1}{20}$ degrees per second

Answer:

$\frac{1}{20}$
