Create a program called vehicleapp.java

Question

Modify Vehicle.java so that it includes an instance variable called milesPerGal. Both Bus and Truck have a method called calculateMPG. The formula for a bus's milesPerGal is 10000/numOfPassenger/horsePower, but for a truck it is 5000/towingCapacity/horsePower. Create a program called VehicleApp.java that displays all information about a specific bus and truck of your choice.
