As with the previous labs, use Diff Checker to compare your programs output to that of the examples before submitting to zyBooks for grading (1) Prompt the user to input the distance to be covered by a vehicle. The values should be doubles. Calculate the total amount of fuel needed as a double. Assume that fuel efficiency is 13.7 miles/liter. Store this value using a constant double variable called MILES_PER_LITER (2 pts) Note: This zyLab outputs a newline after each user-input prompt. For convenience in the examples below, the user's input value is shown on the next line, but such values don't actually appear as output when the program runs. Enter the distance to be covered (miles): 66 Fuel Needed: 4.817518248175182 liter (s) (2) Extend to also calculate and output the amount of fuel in gallons needed to cover the distance (as an integer). Assume a gallon contains 3.785 liters fuel. Store this value using a constant double variable called LITER_PER_GALLON. Hint: For the calculation, use the round method in the Math class to round up the number of gallons. (2 pts) Enter the distance to be covered (miles): 66 Fuel Needed: 4.817518248175182 liter(s) Gallons needed: 2 gallon (s) (3) Extend to also calculate and output the cost needed for the trip. Assume a gallon worth 2.629 $. Store it using a constant double variable called COST_PER_GALLON. (2 pts) Enter the distance to be covered (miles): 66 Fuel Needed: 4.817518248175182 liter(s) Gallons needed: 2 gallon(s) Cost needed: 5.258 $
