A journey between two towns, Pietermaritzburg and Durban, is exactly 90km.
3.1 Use a graph (with at least 5 different speeds in km/h) to model how variation in speed (x) over the journey causes variation in the time taken (y) to complete the trip. HINT: time should be in minutes
3.2 Describe what happens to y (the time) when x (the speed) increases
3.3 Is it possible that a vehicle could travel so fast that the trip could be done in no time at all? Give a reason for your answer
3.4 How does the trend of the graph relate to the question in 3.3?
