Find the constant of variation: word problems

Peter walked a total of 12 kilometres by making 2 trips to school. Later on, he walked 18 kilometres during 3 trips. How many kilometres does Reid walk per trip?

Create a chart.

To find the constant of variation, divide "Total distance walked (kilometres)" by "Number of trips".

The constant of variation is 6.
