    Answer: 50.2 liters

    Step-by-step explanation:

    11 liters = 50km

    Z liters = 228km

    To get the value of Z, cross multiply

    228 x 11 = Z x 50

    2508 = 50z

    Divide both sides by 50

    2508/50 = 50z/50

    50.16 = z

    50.16 has two decimal places, so convert to 1 decimal place by approximation

    50.16 = 50.2

    Thus, 50.2 liters will be enough for 228km
