JAW 6. Fuel Economy A fuel-economy study was carried out for five models of cars. Each car was driven 100 miles, and then the model of the car and the number of gallons used were placed in a line of the file Mileage.txt. Table 5.11 shows the data for the entries of the file. Write a program to display the models and their average miles per gallon in decreasing order with respect to mileage. See Fig. 5.51. The program should create a dictionary of five items, with a key for each model, and a two-tuple for each value. Each two-tuple should be of the form (number of test vehicles for the model, total number of gallons used by the model). TABLE 5.11 Gallons of gasoline used in 100 miles of driving.
