Vincent took 1 1/2 times as long as Marcus to finish a school project. If it took them 30 days in total, how much longer did it take Vincent to complete his work?

Thank you

    Let x = time it takes Marcus, then
    1.5x = time it takes Vincent.
    The total is 30 days; therefore,
    x + 1.5x = 30.
    Solve for x = M
    1.5 x = V.
