Question

the temperature in the morning was -1.4 degrees celsius. by afternoon, the temperature was 5.3 degrees celsius. whats the difference between the afternoon temperature and the morning temperature? select one of four 3.9 degrees celsius -3.9 degrees celsius 6.7 degrees celsius -6.7 degrees celsius remaining attempts: 1

Explanation:

Step1: Identify the formula for temperature difference

To find the difference between the afternoon temperature (\(T_{afternoon}\)) and the morning temperature (\(T_{morning}\)), we use the formula: \( \text{Difference} = T_{afternoon}-T_{morning} \)

Step2: Substitute the given values

We know that \( T_{morning} = - 1.4^\circ\text{C} \) and \( T_{afternoon}=5.3^\circ\text{C} \). Substituting these values into the formula, we get:
\( \text{Difference}=5.3 - (-1.4) \)

Step3: Simplify the expression

Subtracting a negative number is the same as adding its positive counterpart. So, \( 5.3-(-1.4)=5.3 + 1.4 \)
Calculating the sum: \( 5.3+1.4 = 6.7 \)

Answer:

6.7 degrees Celsius
