Real-life graphs (conversion, cost and travel graphs)Exam-style questions

Read real-life graphs both ways: change units with a conversion graph (and scale a reading beyond its edge only when the line starts at zero), read a fixed charge and a cost per hour off a cost graph, compare two tariffs where their lines cross, and turn a travel graph into a story: stops, speeds in km/h, the journey home, drawing the next part, and two journeys on one graph.
