    The time taken for landscaper 1 is 5.4 hours.

    The time taken for landscaper 2 is 3.6 hours.

    Step-by-step explanation

    Let the time taken by the landscaper 1 to complete the job be ‘a’

    Let the time taken by the landscaper 2 to complete the job be ‘a/1.5’

    a + (a/1.5) = 9

    (1.5a + a) /1.5 = 9

    2.5a/1.5 = 9

    5a/ 3 = 9

    a = 27/5

    a = 5.4 hours

    a/1.5 = 5.4/1.5

    a/1.5 = 3.6 hours

    The time taken for landscaper 1 is 5.4 hours.

    The time taken for landscaper 2 is 3.6 hours.
