    Answer: 1 hour

    Step-by-step explanation:

    Let distance1 = x km

    Distance2 = 144 - x

    Speed S1 = 63 kph

    Speed S2 = 81 kph

    Time = Distance / Speed

    When the jets pass each other

    (144-x) / 81 = x/63

    63 (144-x) = 81x

    9072 - 63x = 81x

    x = 9072 / 144

    x = 63 km

    Time = 63/63 = 1 hour
