You've just returned from a road trip and are curious about your car's fuel consumption during the trip. Unfortunately, you didn't reset the counter before leaving home. You do know the average consumption of your car and the previous distance you have traveled in that vehicle.
Write a function that takes two pairs of input
(before, after) and returns the calculated average fuel consumption of your car during your trip, rounded to the first decimal place.
Both pairs consist of two valid numbers:
- average fuel consumption of the car (l/100km, float)
- previous distance traveled (km, integer)
Example: BEFORE AFTER DURING avg. cons, distance avg. cons, distance avg. cons [l/100km] [km] [l/100km] [km] [l/100km] [ 7.9 , 100 ] , [ 7.0 , 200 ] --> 6.1 [ 7.9 , 500 ] , [ 7.0 , 600 ] --> 2.5 [ 7.9 , 100 ] , [ 7.0 , 600 ] --> 6.8
Have fun coding!
