$= 20 k m$ $color(purple)(=20km)$

Explanation:

$18$ $18$ $k m$ $km$ $\div$ $-:$ $9$ $9$ $trips$ $"trips"$

$=$ $=$ $2$ $2$ $k m$ $km$ $per trip to school$ $"per trip to school"$

$Now that we know that Elise walks 2 km to walk to school, we multiply that by 10$ $"Now that we know that Elise walks 2 km to walk to school, we multiply that by 10"$

$2$ $2$ $k m$ $km$ * $10$ $10$ $t r i p s$ $trips$

$=$ $=$ $20$ $20$ $k m$ $km$

$:.$ $color(purple)"Elise walked 20 km in total"$

This is the same as the other answer. It just looks different.

$20" Km"$

Explanation:

Using ratio but in fraction format.

$("distance walked in Km")/("trip count") -> 18/9$

Let the unknown distance be represented by $x$

$("distance walked in Km")/("trip count") ->18/9-=x/10$

Multiply both sides by 10

$x=10xx18/9$

$x=10xx2 = 20$

$20 " Km"$
