For example: (0,0) is the starting point because no time has passed and no distance has been travelled. (10,1000) shows that after 10 minutes has passed a distance of 1000 m has been travelled.

Example: Using the gradient or slope of a distance - time graph to work out the speed of an object Calculate the speed of the object represented by the green line in the graph below, from 0 to 3 s.
