Certainly! Let's solve this question step-by-step.

First, write the expression as:

[tex]$3k$[/tex]

Since Yuna ran three times as many kilometers as [tex]\( k \)[/tex], the expression to calculate the total distance she ran is [tex]\( 3k \)[/tex].

Second, substitute [tex]\( 12.2 \)[/tex] in for the variable [tex]\( k \)[/tex]:

[tex]$3 \times 12.2$[/tex]

Third, multiply [tex]\( 3 \)[/tex] by [tex]\( 12.2 \)[/tex]:

[tex]$3 \times 12.2 = 36.599999999999994$[/tex]

The answer is:

[tex]$36.599999999999994$[/tex]

So, Yuna ran [tex]\( 36.599999999999994 \)[/tex] kilometers.
