The question, in short
From a speed–time graph rising to 10 m/s by 10 s, constant to 30 s, then falling to zero at 60 s, calculate the total distance travelled.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 2 marks
- 1Distance = area under the graph
- 21/2 × 10 × 10 + (30 − 10) × 10 + 1/2 × (60 − 30) × 10
- 3= 50 + 200 + 150 = 400 m
