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

d = t + 6

The variable t represents the number of trips he has made, and the variable d represents the total distance walked in kilometers. How many trips will Farid have to make in all to walk a total of 20 kilometers?

1 answer

To find out how many trips Farid needs to make to walk a total of 20 kilometers, we can use the equation provided:

\[ d = t + 6 \]

We want to find the value of \(t\) when \(d = 20\). So, we can set up the equation:

\[ 20 = t + 6 \]

Next, we will solve for \(t\).

First, subtract 6 from both sides:

\[ 20 - 6 = t \]

\[ t = 14 \]

Therefore, Farid will have to make 14 trips to walk a total of 20 kilometers.
