A, ok, ang constant nyo yung number of kilometers. Ako naman, ang constant ko yung number of liters. After I reach the halfway mark, I refill the tank to full tapos I reset the trip meter. I take note of how many liters yung naipasok pag refill ko from the halfway mark hanggang mapuno. Pagdating ko ng halfway mark ulit, makikita ko na kung gano kahaba yung natakbo ko, and yun yung dinidivide ko with the number of liters na naipasok pag refill. I don't depend on the number of kilometers to know when to fill up, I just depend on the halfway mark sa gas meter. It's more logical for me to keep the number of kilometers travelled as the variable, kasi siya yung nasa numerator, haha! Weird ba? Well, just do what works for you, basta alam ko, ok ang fuel consumption namin.
Have a fuel-efficient day everyone!
