The question, in short

Use the travel graph of distance against time from 12 00 to 16 00 to interpret the journey, explaining a flat section and identifying the fastest interval with a reason.

Summarised in our own words. Use the official paper for the exact wording and the diagram.

Part (a) · 1 mark

State what the horizontal section of the graph between 14 20 and 14 40 shows about the student's movement.

  1. 1Between 14 20 and 14 40 the line is horizontal (distance stays at 4 km)
  2. 2The student is stationary

AnswerStudent is stationary

Part (b) · 2 marks

Give the two times between which the student travels fastest and explain why, using the graph's steepness.

  1. 113 00 to 13 20: 4 km to 7 km, 3 km in 20 min = 9 km/h, the fastest section
  2. 213 00 and 13 20, because the gradient is steepest

Answer13 00 and 13 20, because the gradient is steepest
