#31. Calculate the overall distance travelled by the object in the graph.

enter answer here...

#32. Calculate the distance travelled by the runner in the velocity/time graph.

enter answer here...

The area under the graph = distance travelled

Split the graph into triangles and rectangles and calculate the areas. Then add together the areas.

Area of a rectangle = Length x Height

Area of a triangle = 1/2 x Length x Height

90m 120m 180m = 390m

NOTE: the graph starts at one second and not 0. Don’t be fooled, look at the axes carefully before attempting a question.
