# Britney has already walked 8 kilometers this week, plus she plans to walk 1 kilometer during each trip to school. After 3 trips to school, how many kilometers will Britney have walked in total?

If she walks a total of $1$ $k m$ each day it will be $8 + 3 \left(1\right) = 11$ $k m$.
If she walks a total of $2$ $k m$ each day (to school and home again) it will be $8 + 3 \left(2\right) = 14$ $k m$.
It's not clear whether she is just walking to school each day ($1$ $k m$), or whether she is walking to and from school each day ($2$ $k m$).
The total distance walked will be $8 + 3 n$ where $n$ is the number of km per day.
