Problem
1. Explain the difference between a parameter and an argument.
2. (a) Define a function called liters needed that takes a value representing a distance in kilometers and a value representing gas mileage for a vehicle and returns the amount of gas needed in liters to travel that distance. Your definition should call the function convert mileage that you defined as part of a previous exercise.
b) Verify that liters needed(150, 30) returns 11.761938367442955 and liters needed(100, 30) returns 7.84129224496197.
(c) When liters needed is called with arguments 100 and 30, what is the value of the argument to convert mileage?
(d) The function call liters needed(100, 30) results in a call to convert mileage. Which of those two functions finishes executing first?
