    amount of time it'll take Henry and Louisa = 6/5 hours

    Step-by-step explanation:

    Number of hours it takes Henry = 2hrs

    Henry's one hour work = 1/2

    Number of hours it takes Louisa = 3 hrs

    Louisa's one hour work = 1/3

    Hence Louisa and Henry one hour work = 1/2+1/3 = 5/6

    Hence amount of time it'll take Henry and Louisa = 6/5 hours
