For every 1,000 feet that it climbs, the outside temperature drops 20 degrees Fahrenheit. What is the rate of temperature change in degrees Fahrenheit per foot? Complete the steps below to answer the question. Part A Write the change in elevation and the change in temperature as rational numbers. square v

## Step 1<br />The problem provides us with two quantities: the change in elevation and the change in temperature. The change in elevation is given as 1,000 feet and the change in temperature is given as 20 degrees Fahrenheit.<br /><br />## Step 2<br />We need to express these quantities as rational numbers. A rational number is a number that can be expressed as the quotient or fraction \( \frac{p}{q} \) of two integers, where \( p \) is the numerator and \( q \) is the denominator.<br /><br />## Step 3<br />In this case, the change in elevation is 1,000 feet, which can be written as \( \frac{1000}{1} \). This is because the change in elevation is a whole number, and any whole number can be expressed as a fraction with a denominator of 1.<br /><br />## Step 4<br />Similarly, the change in temperature is 20 degrees Fahrenheit, which can be written as \( \frac{20}{1} \). This is because the change in temperature is also a whole number, and any whole number can be expressed as a fraction with a denominator of 1.
