Question details

Draw a distance–time graph for an object moving in a straight line. The graph should show how the distance (in metres) changes with time (in seconds). A tangent to the curve is drawn at P.

(a) How long does the object’s journey last, according to the graph? 

b) What is the average speed of the object over its journey? 

c) Find the object’s instantaneous speed at the 20 s mark. On the graph, show CLEARLY the points you used to work out the answer to this question AND draw the triangle formed by your points.
