Each line segment of a distance-time graph represents one part of a journey ... total distance travelled is 32 miles. Plot the last two points (13:00, 32) and draw the line segment for this ...

Discover how to easily calculate the distance between two points in Cartesian coordinates. A simple and effective trick!

We can also use Pythagoras to find the distance between two points. Plot the coordinates onto a graph. Join up A and B to show the line AB then form a right-angled triangle.
