In the book, The Lion, the Witch, and the
Wardrobe (C.S. Lewis, 1961), a group of
children find a portal to the world of Narnia
where time passes at a different rate than on
Earth. The children are in Narnia for 15 years while only 5 minutes pass on Earth. Peter, the oldest child in the group, is 13 when he enters Narnia. Write a linear equation that shows Peter's age n in Narnia for each minute m that passes on Earth.
