MAP4C: Foundations for College Mathematics, Grade 12, College PreparationUnit 1: Mathematical ModellingActivity 1: Introduction to Mathematical ModellingAssignment Solutions1. The following graph shows the fuel consumption for a vehicle driving at different speeds. Use the graph to answer the questions below.a) Does the relationship between fuel consumption appear to be linear? Explain.
b) At what driving speed is fuel consumption the least?
c) Suppose you drive to a friend’s cottage, a distance of 300km. Determine the amount of money you would save over the return trip by driving at 90 km/h versus 120 km/h. Assume that gas costs $1.12per litre.
