Welcome to your Graphs Name Email 1. The graph shows the conversion: 5 miles = 8 km. Using the graph, estimate: a) How many km are 18 miles? 2. Cyclist A leaves at 9:00 am from Town P to Town Q (60 km). His speed = 20 km/h. Cyclist B leaves at 10:00 am, speed = 30 km/h. At what time will B catch up with A? 3. A conversion graph shows £1 = $1.25. a) How many dollars are £240? b) How many pounds is $500? 4. A train covers 180 km. Graph shows: 0–2 hrs → 100 km 2–3 hrs → stopped 3–4 hrs → covers 80 km. What fraction of total time was spent moving? 5. The graph converts °C to °F: F = (9/5)C + 32. a) Convert 30°C into °F. 6. A conversion graph shows: 4 kg of apples = $10. a) What is cost of 7.5 kg apples? 7. A graph shows oil is delivered to a tank: 0–15 min: +300 L 15–25 min: no change 25–40 min: +500 L. a) What was the average rate of delivery in last stage? 8. Car A leaves city at 8:00, speed 50 km/h.
