Develop a model for the effective gas mileage (call it E) as a function of speed (S) for a ¡°typical¡± car (you should be able to find the necessary information to develop this model for your own car). This model should be valid for 55 ¡Ü S ¡Ü75 (it will be apparent from part a while a single function for all speeds would be difficult). State all of your assumptions.
I am completely lost. Help?
