Each line segment of a distance-time graph represents one part of a journey. A distance-time graph, sometimes referred to as a travel graph, is a way of representing a journey. It is helpful to have ...

Real life situations such as travelling over time and across distance can be drawn on a graph. Exact distances and times are plotted on the graph. These are shown as co-ordinates. These points are ...

The wide diameter of a graph is a natural generalization of diameter in a graph when we take account of the connectivity of the graph. In this paper, we define the generalized wide diameter of a graph ...
