Answer :
To solve the problem, we need to evaluate how many kilometers Yuna ran, given that she ran three times as many kilometers as a particular number of kilometers, [tex]\( k \)[/tex], which is 12.2.
Let's go through the steps:
1. Identify the Expression: We need to determine how to express "three times as many kilometers" in terms of the variable [tex]\( k \)[/tex]. This can be represented by the expression [tex]\( 3 \times k \)[/tex].
2. Substitute the Value: We know that [tex]\( k \)[/tex] is given as 12.2. So, we substitute 12.2 into the expression for [tex]\( k \)[/tex].
3. Calculate the Multiplication: Perform the multiplication:
[tex]\[
3 \times 12.2 = 36.6
\][/tex]
Therefore, Yuna ran 36.6 kilometers.
