E2.9.4
Level
Extended

Exam points

  • split the region under the graph into rectangles, triangles or trapezia with time as width
  • add all signed section areas to obtain total distance in units consistent with speed and time
  • combine the area-derived distance with a remaining distance or comparison to solve another value
