The main aim of this section is to introduce the distance-time graph as a mathematical model of a journey.
Like any mathematical model, a distance-time graph stresses some features of the situation it claims to represent and ignores others. Bear this in mind as you work through this section, and note for yourself which aspects of a journey are described graphically, and which do not feature in the model.
You will need graph paper for this section.
