Distance and time graph
As you can see , this is a Distance and time graph , At the point A you could see the time is 5 minutes and following distance , at point B it is 10 minutes and following distance and at point C it is 15 minutes and the folloing distance.
In section A, the graph slopes up gently, showing that the coach was travelling at a slow speed.
In section B, the graph becomes steeper. The distance of the coach from its starting point is increasing more rapidly. It is moving faster.
