Task 1: Line Graph (May 3, 2025)

The line graph illustrates the nitrogen oxide emissions (in grams per kilometre) emitted by four types of transport — buses, lorries, petrol car, and diesel car — at speeds ranging from 10 to 130 kilometres per hour.

Overall, buses and lorries emit considerably more nitrogen oxide, while petrol and diesel cars release much less, with diesel cars being the least polluting. In addition, petrol and diesel cars produce nearly the same amount of nitrogen oxide at all speeds, while emissions from buses and lorries vary significantly with speed.

Buses emit by far the most nitrogen oxide, beginning with 40 grams per kilometre when travelling at 10km/h. This figure steadily declines to 25 grams per kilometre at a speed of 60 km/h. However, emissions rise again, exceeding 40 grams per kilometre at 130 km/h. Lorries produce the second-highest emissions, starting at around 33 grams per kilometre at 10km/h. Emissions then continue to decline, reaching a low of just under 20 grams per kilometre at 90km/h. After that, there is a steady rebound to 25 grams per kilometre at 130km/h.

Petrol and diesel cars show nearly flat trends in nitrogen oxide emissions across all speeds. Petrol cars emit just under 10 grams per kilometre at 10km/h; this figure dips slightly at mid-range speeds and returns to the same level by 130km/h. Diesel cars release around 7 grams of nitrogen oxide emissions per kilometre at 10km/h, with emissions falling slightly to 5 grams at 40km/h and remaining steady at that level up to 130km/h.

Task 1: Line Graph (May 3, 2025) This one was quite tricky. At first glance, I couldn’t tell whether it was a comparative or a trend-based graph; then I realized it actually serves as both. @otaboyevblog
