    The answer to your question is : 80 minutes

    Step-by-step explanation:

    Data

    Mark = 120 minutes

    Alexis = 240 minutes

    Together = ?

    We need to write an equation, we consider that in 1 minute, Mark loads 1/120 and Alexis 1/240. Then the equation is:

    1 = x/120 + x/240 1 = truck uploaded; x = time in minutes

    Solve it 1 = (2x + x) / 240

    240 = 3x

    x = 240/3

    x = 80 minutes
