Answer :
To solve the problem, let's go through the steps:
1. Write the expression: Yuna ran three times as many kilometers as represented by the variable [tex]\( k \)[/tex]. The expression that represents this is [tex]\( 3 \times k \)[/tex].
2. Substitute 12.2 for the variable [tex]\( k \)[/tex]: Replace the variable [tex]\( k \)[/tex] in the expression with the given value, which is 12.2. The expression becomes [tex]\( 3 \times 12.2 \)[/tex].
3. Multiply 3 and 12.2: Perform the multiplication, [tex]\( 3 \times 12.2 \)[/tex], which gives you the total kilometers that Yuna ran.
The answer is approximately 36.6 kilometers.
