The question, in short
Speed–time graph for a bus: speed rises from 0 to 15 m/s by 20 s, stays at 15 m/s until 140 s, then falls to 0 at 190 s. Calculate the total distance travelled.
Summarised in our own words. Use the official paper for the exact wording and the diagram.
Solution · 3 marks
- 1Distance = area under the graph (a trapezium)
- 2Parallel sides: 190 s and 140 − 20 = 120 s, height 15 m/s
- 3Distance = 1/2 × (190 + 120) × 15
- 4= 2325 m
