Question

This equation shows how the total distance Mia has walked depends on the number of trips she has made to school.

d = t + 13

The variable t represents the number of trips she has made, and the variable d represents the total distance walked in kilometers. After 2 trips to school, how many kilometers will Mia have walked in total?

Answer 1

To find the total distance Mia has walked after 2 trips to school, we can substitute \( t = 2 \) into the equation:

\[ d = t + 13 \]

Substituting \( t = 2 \):

\[ d = 2 + 13 \]

\[ d = 15 \]

So, after 2 trips to school, Mia will have walked a total of 15 kilometers.
