    Answer:

    It will take them 8 minutes to work together

    Step-by-step explanation:

    Trent: 10 minutes = 1/10

    Lois: 40 minutes = 1/40

    Together: x minutes = 1/x

    1/10(10x) + 1/40(10x) = 1/x(10x) –> x + 1/4x = 10 –> 5/4x = 10

    10/1 divided by 5/4x = 10 times 4 divided by 5 = 8 minutes
